At a lower atmospheric pressure, there's less force pushing down on the surface of the liquid meaning the energy threshold to jump from liquid to gas is lower. Since it requires less energy to become a vapour it can boil at a lower temperature -- or room temperature (temperature is simply the average kinetic energy of atoms in a substance)
Not accurate, have you wondered though why you can't cook (boil) an egg in this water? Bubbles forming when you boil water to cook ...pasta and bubbles forming in this experiment are one and the same: Gas molecules forming and escaping from the water. The difference is the method used. One is the introduction of energy (heat) and the other is reducing the atmospheric pressure around the water. Think why it is recommended to add salt in the pot for cooking: Because it helps the water reach the recommended higher energy point (e.g. at least or a bit higher than 100C) and faster. Bottom line is you cannot boil (cook) hard boiled eggs in this kind of vacuum environment. so you guys should stop saying, boiling. It is not!
@@XwpisONOMA Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. Wikipedia It's literally boiling.
@@XwpisONOMA Cooking an egg is caused by the denaturation of proteins inside the egg. All proteins denature at a high enough heat. As the proteins denature, they permanently change shape, although an egg has been "un-boiled" in a Nobel Prize winning experiment in 2015. Boiling water is fundamentally different to boiling an egg. Boiling water changes the state of the water, and boiling an egg denatures the proteins inside the egg. Hope this helps :)
I was studying physical equilibrium in chemistry and I was reading about what is boiling point(Temperature at which vapor pressure of liquid become equal to external pressure). Then I thought that if the external pressure is reduced then the boiling point will also be reduced and then I searched on RUclips what will happens when we boil water in vaccum and then this masterpiece video came to me. Thank you very much bro. You always give me practical knowledge of physics and chemistry.
@@noahway13 It gives the water enough energy to overcome the pressure of the air. Allowing it to basically jump out of it's liquid state. It's the difference between jumping on the moon and earth.

1:22 Your explanation for boiling isn't 'wrong' per-se, but it's incomplete. What you describe fits the definition of 'evaporation' better than boiling. Boiling is when the vapor pressure of the liquid (which changes with temperature) exceeds the pressure exerted on the liquid by the surrounding atmosphere. This helps to explain why reducing pressure can induce boiling without changing the temperature (reduction in external pressure-no change in internal vapor pressure). It also explains why raising the temperature, as is more traditionally done, causes boiling (no change in external pressure, but a rise in internal 'vapor pressure' of the liquid).
Do you know if the bubbles in the water (the air dissolved in the water) are also just pure nitrogen molecules? Or do the nitrogen and oxygen molecules always stay close to eachother to form air (the bubbles)). Hope I'm clear ineough :)
@@Scrungge Hi Berton. I'm not clear on if you are asking a question related to my post? The 'air bubbles' in boiling water are actually water vapor gas bubbles, not 'air' at all. No nitrogen involved either. Perhaps I'm not clear on what you are asking. EDIT: I just re-watched the video because it has been some time. I see you are probably referring to the bubbles he mentions at 2:15. The answer to your question about whether those air bubbles are truly mixed air with the same gas composition or are pure nitrogen or oxygen, etc. I do not know.
If I'm not mistaken, the freezing point of water is also determined by pressure. It probably doesn't have to do with residual warmth from the vacuum chamber, since the water itself was at -0.1c.

Great stuff, would have been nice to have a little device to drop an ice seed into the 0c water to see how the vacuum cooled water would react, would there be enough nucleation from impurities considering the air was pulled out of it?
its sick!!!! ya pressure will speedy back to normal and at normal pressure water will freeze will be resublimation, from gas to ice instantly but it will be like implosion. it will suck some air and idk what will do but its dangerous
DANG JOS it will freeze because its below 0°C it just doesnt freeze while in the vacuum chamber because changing the pressure decreases the point at which it does so (just like it decreases the temperature needed to boil)
+Lars L Lowering the pressure over water actually increases its melting temperature; it doesn't decrease it. I would question the accuracy of his thermometer. Even if the thermometer is accurate, the most likely reason for the lack of freezing is super cooling. Not a reduction of pressure. The triple point of water is actually at 0.01 C
looking at the triple point graph of water, increase in melting temperature while lowering pressure only happens at 212.9 MPa until 10MPa, the rest of the pressure is opposite of what you said. Triple point only means at that pressure all 3 states of that matter can exist together. I would not question that thermometer, it is only a matter of time that the water turns into solid/gas because the pressure definately are below the triple point of water due the the temerature kept decrease in the water, at one point the temperature surely will stop and that will be when the freezing happens. @DANG JOS you should take a good look at the graph seriously...

Why is the surrounding glass is cooler? When water heats up and boils, it takes in energy to overcome intermolecular forces of attraction between each H2O molecule, thus turning into a gaseous state. This is also called an endothermic reaction. (Takes in energy) In this case, since there is no constant supply of heat energy supplied, they will absorb energy from its surroundings to break the bonds, causing the surrounding glass panels to cool. (Internal temperature of water should remain the same) yay finally something I learnt from school is used to mke me seem smart even though Im not xp
+lokesh kumar the reason is actually because my thermometer fell in the water and the screen went out after it stared boiling:) but that is why I did it again at the end so you can see the temperature drop while boiling
So would the water keep boiling off at a certain pressure, or would it stop boiling once it cools to a certain point? Also would you have to keep the vaccuum running because the boiling water turns to gas and that gas repressurizes the chamber? Thanks 😃
The key here is pressure is directly proportional to temperature, if you the reduce the pressure as in vacuumed space you also reduce the temperature or the boiling point of a liquid. As shown the container with liquid inside is vacuumed there by reducing the press\temp, so the temperature around area of the glass container no matter how low it is will be absorbed by the liquid in the glass and cause to boil. Same principle is applied in refrigeration.
i see.. so this just added to my understanding of what happens on air separation system of oxygen, argon and nitrogen. although it doesn't technically like the vacuum chamber, like the opposite way since it compressed the air to higher pressure and not suck it out, the boiling part was the same to the way it form just the fog then the watery fog it produce was the high purity liquid oxygen. Imagine at negative degree it says boiling point? So its not about the heat, but the state it starts to evaporate.. thank you for this experiment and it enlighthen me on the field of work I was on.
Love You Bro!!......I am a Auto Tech, and I wanted to know exactly why we use a vacuum pumps...Your explanation helps me, be better and more informative...We use vacuum pumps to boil the moisture out of the AC system...I can clearly see why moisture is the enemy in my work...
Kulvis Flabu when we use compressed can (paint/ butane) the contents are actually decompressing, isn’t it? So I think the cooling effect can be attributed more to the movement of the propellant’s molecule rather than the boiling of actual liquid content. Same concept with refrigerants in aircons and refs. Or are these all the same principles?
One question in the end, when temperature of water reached freezing at normal pressure. Would the water freeze instantly if you would open vacuum chamber or would the temperature of water rise?
Neither. The temperature decreases because it boils. That means that for it to increase it would have to undergo the reverse process. When you open the chamber it does, and it condensates, but on the walls, no contact with the water, so the heat doesn't go back in. Plus, most of the vapour which extracted the heat in the first place was taken out by the pump as it tried to maintain a vacuum. Freezing also needs a nucleus. So unless you tap on the glass, it wouldn't freeze in normal pressure either at sub zero temperatures.
check it. pressure are at left temperature at down. liquid nitrogen will make gas. get random point at nitrogen when he is liquid and go down to see what will be when you lower pressure. it will be gas like water but if nitrogen would be solid it will do nothing.
blazing dino. its brilliant check that diagram LIQUID(not solid) nitrogen will be gas at vaccum. i want see that! liked i want see how it will look. beliving the diagramnitrogen will become gas and water just like disapear.i think it will be boiling almost invisible liquid then it will disapear, it will change into then white gas that just become invisible after while. i want see it.
+The Action Lab To add to the definition of boiling, it is when the vapor pressure of the liquid equals the atmospheric pressure. As I learned from a physics professor once, the internal pressure of a steam bubble is equal to the vapor pressure, and if that is smaller than the outside pressure, then the bubble will literally collapse back into the liquid. This is why, when you put water on a hot stove, you see water on the bottom get hot enough to form a bubble, but it collapses before reaching the top. This is of course because the water isn't yet hot enough to sustain the steam bubbles
If we could create a breathing apparatus that used a vacuum to take air out of the water potentially we create oxygen tank-free scuba gear. That would be cool.
+Daniel Padgett that's a cool thought! So a small vacuum pump connected to a tube that continually brings in new liquid that has the pressure lowered until the dissolved air is released. That air is then returned to normal pressure. It wouldn't be much volume of air per volume of liquid though, so I don't know how plausible it would be, but that would be cool.
Of course, development could create a strong compact vacuum that would increase water flow and air supply to a faster rate. All ideas can be improved upon. Love your videos they're great and very informative.
The Action Lab way late to the game on this, but "normal" pressure in this case wouldn't be the same as on land. Keep in mind, you're under water, so you're under a lot of pressure. The air you breathe would have to be pressurized, too. If you went to the bottom of a swimming pool with a rigid tube, and tried to breathe through it, you'll discover your diaphragm isn't strong enough to match the pressure at much of any depth. PLEASE don't try this, as there are inherit dangers involved. I'm a diver, both recreational and (retired) commercial. As such, I'm studied in things like gas laws, and basic human anatomy (at least in so much as what parts of the body are most affected by pressure changes. Don't use yourself as a human guinea pig trying to test gas law. I don't want to appear in court when you pop your lungs, shatter teeth, blow out your ear drums, etc.
use electricity to hydrolysis for pure oxygen supply under water and it done according to internal combustion system as we need water intake in it's pure forms so we need filter and a efficient battery will provide power to this setup and underwater we living our lives forever without the need of atmospheric oxygen battery are charge with waves energy or solar energy
Interesting. That would be roughly the situation on Mars. The atmospheric pressure on the red planet is so low that water boils. Basically one could say that the atmosphere of Mars is rather a bad vacuum.
Hey Action Lab, is it possible we could see what a fire would look like in the Vacuum chamber if you used an oxidizer as a fuel source? That would be pretty cool :D
Cody's Lab YT channel did that. The result was that nothing sustained burning including gunpowder, rocket fuel, and perchlorate explosives. It would smolder in the laser but not actually ignite.
thank you soooo much for this video it helped me understand how vacuum chambers in facilities actually work and why mercury is used to cool down produce.
Sir I think it did not froze because as Boiling Point differ at certain Pressure same will happen to the Freezing Point it will increase also instead of 0 to maybe negative something depending on ambient pressure.
Hi, do you know what type of vacuum pump can be used without desiccant for this experiment ? we are trying to setup this demonstration as a science project work
this is earth, a vacuum on the surface of earth is still affected by earth's gravity,so it should be no difference.And they also need a larger vacuum chamber for that :P Things are different at space station or satellite is because they are not stationary, they move alot (have momentum) to counteract the gravitational pull so that they wont fall down to earth. Point is Vacuum simply state that that space has no gas in it
Since the majority of mass of the vacuum chamber is the solid walls of the container, removing the air from inside will not noticeably change its weight. This is why vacuum airships that could exist in concept, have never become a reality. It is impractical to build a lighter-than-air vessel with walls rigid enough to support the vacuum inside the vessel.
Excellent. You just answered my two questions, does it boil, and what is the lowest temperature. It would be interesting to see this with a different liquid, in particular a paint. I was watching the painting of the outside of the spaceship during the opening credits of Red Dwarf, and it finally occurred to me after twenty-five years to ask: is this even possible?

LONER or your a nerd
I think it didn't freeze because -as it is tap water- it has different things desolved in it like salt, Magnesium, etc and with the ions in it, the freezing point of it decreased, thus never freezing while boiling. Long ago, Cody from Cody's Lab did the same thing, but I believe he used destilled water and managed to freeze it.
That's not what sublimation means. Sublimation means that something goes from the solid phase to the gas phase without ever being in the solid phase that usually is in between.
Can you put a small open bottle of water in the vacuum chamber and see if you can freeze it? Even if It doesn't freeze without you "agitating" the water.
I thought I was gonna see the water fully evaporate, leaving behind a gooish or even dry-ish mix of what was once the food colorant, and then we'd get to see how quickly it'd turn back into liquid the moment you undid the vacuum, but I guess the water turning into vapor would forcefully be taken out of the vacuum as the mechanism does the vacuuming and it'd never come to what I was thinking xD Cool video, I knew pressure affected the boiling and not just temperature, but I didn't know how noticeably different it'd be among locations within Earth that humans could be at xP
+Neil Baxter because the definition of boiling is when the vapor pressure of the liquid is greater than the pressure surrounding the liquid. Bubbling is when there are simply bubbles of a gas in a liquid. Boiling and bubbling are completely different phenomenon.
trees are cool, especially redwoods. Fascinating. If there’s no heat being applied, how do trees release gaseous water in the leaves? Liquid in roots to gas in leaves. Increase pressure, decrease temperature. By that logic, trees are constantly boiling water. I guess the same logic is applied to other plants.
Hi! very interesting experiment! What do you think going to happen to the pH? the water going to loose CO2, than carbonic acid, and the pH will increase?
Hi Sir, currently I am working in a project of converting water to steam by a vacuum chamber with water coming in to the chamber and the idea is to have a pressure that a allow that water to boil straight away once is in the chamber. Any recomendations to make this happen?
Seems very logical. If you use a pressure cooker water boils at a higher temperature. So if an increase in pressure increases the boiling temp then a decrease should decrease the boiling temp.
When water boils does the atmospheric pressure become higher? Also do you have to continue vacuuming in order for the pressure to remain constant? Or can you vacuum a chamber and let it sit at that atmospheric pressure then warm up the chamber to warm up the water and let it boil at a low temperature?
the pressure will increase just enough to stop the boiling effect, yes you have to keep pulling vacuum. the water will turn to ice with a good vacuum pump. you can also heat up a bottle of water to boiling point then take it off the flames put a cork stopper. the water will stop boiling after a short time but by placing your hand on the bottle it will start to boil again. this is because you remove heat from the trapped air and it creates a vacuum in the bottle and the water boils.
the water in that last demonstration was never going to freeze until after you released the vacuum, for the same reason that it was still boiling. do you mean raising the pressure also heated the sample enough to prevent freezing?
Boiling occurs whenever the vapor pressure of the liquid and the environment pressure are equal. Evaporation occurs at all temperatures between the melting point and the boiling point, (fastest evaporation speed at boiling point)
If you stop the vacuum pump and close the vacuum in the vacuum chamber, does the boiling continue? or the pump must always work. I mean if the pressure remains at -1 bar in the vacuum chamber after the pump is stopped, but the vacuum chamber keeps the vacuum at -1 bar further.
If you put ice in a vacuum chamber would it melt under vacuum and refreeze once pressure returns? May have to do this in a walk in freezer so the temperature stays freezing?
so it is possible to drown a fish
Mind blown
Wow.
Dont change the aquarium water or airate it.. and the fish will drown..
Yes fishkeepers know this, when oxygen is low in water fish drown the first sign of low oxygen is fish going to the top of their water to breathe.
Is it possible to fly on air without wings?

U r showing all in practicall...nice
Why don't you put liquid nitrogen to see if it is water like..
ya i think it will but i need check something it will do something

check it. pressure are at left temperature at down. liquid nitrogen will make gas. get random point at nitrogen when he is liquid and go down to see what will be when you lower pressure. it will be gas like water but if nitrogen would be solid it will do nothing.
blazing dino. its brilliant check that diagram LIQUID(not solid) nitrogen will be gas at vaccum. i want see that! liked i want see how it will look. beliving the diagramnitrogen will become gas and water just like disapear.i think it will be boiling almost invisible liquid then it will disapear, it will change into then white gas that just become invisible after while. i want see it.
+Blazing Dino I did do liquid nitrogen in the vacuum chamber already on this channel and eventually it froze up solid nitrogen. It was really cool.
NICE EXPERIMENT DUDE

Water wants to be a gas, but is kept in a liquid form by atmospheric pressure. This is why water boils in a vacuum correct? Great video!
wow, so interesting! l loved it!
+The Action Lab To add to the definition of boiling, it is when the vapor pressure of the liquid equals the atmospheric pressure. As I learned from a physics professor once, the internal pressure of a steam bubble is equal to the vapor pressure, and if that is smaller than the outside pressure, then the bubble will literally collapse back into the liquid. This is why, when you put water on a hot stove, you see water on the bottom get hot enough to form a bubble, but it collapses before reaching the top. This is of course because the water isn't yet hot enough to sustain the steam bubbles
+DANG JOS yes the vapor pressure =to atmospheric pressure is the better definition of boiling.
If we could create a breathing apparatus that used a vacuum to take air out of the water potentially we create oxygen tank-free scuba gear. That would be cool.
+Daniel Padgett that's a cool thought! So a small vacuum pump connected to a tube that continually brings in new liquid that has the pressure lowered until the dissolved air is released. That air is then returned to normal pressure. It wouldn't be much volume of air per volume of liquid though, so I don't know how plausible it would be, but that would be cool.
Of course, development could create a strong compact vacuum that would increase water flow and air supply to a faster rate. All ideas can be improved upon. Love your videos they're great and very informative.
The Action Lab way late to the game on this, but "normal" pressure in this case wouldn't be the same as on land. Keep in mind, you're under water, so you're under a lot of pressure. The air you breathe would have to be pressurized, too.
If you went to the bottom of a swimming pool with a rigid tube, and tried to breathe through it, you'll discover your diaphragm isn't strong enough to match the pressure at much of any depth. PLEASE don't try this, as there are inherit dangers involved.
I'm a diver, both recreational and (retired) commercial. As such, I'm studied in things like gas laws, and basic human anatomy (at least in so much as what parts of the body are most affected by pressure changes.
Don't use yourself as a human guinea pig trying to test gas law. I don't want to appear in court when you pop your lungs, shatter teeth, blow out your ear drums, etc.
use electricity to hydrolysis for pure oxygen supply under water and it done according to internal combustion system as we need water intake in it's pure forms so we need filter and a efficient battery will provide power to this setup and underwater we living our lives forever without the need of atmospheric oxygen
battery are charge with waves energy or solar energy
according to indian literature it's already done by nivat kavacha rakshasa in india in ancient times of vedic kaal
Interesting. That would be roughly the situation on Mars. The atmospheric pressure on the red planet is so low that water boils. Basically one could say that the atmosphere of Mars is rather a bad vacuum.
Hey Action Lab, is it possible we could see what a fire would look like in the Vacuum chamber if you used an oxidizer as a fuel source? That would be pretty cool :D
Cody's Lab YT channel did that. The result was that nothing sustained burning including gunpowder, rocket fuel, and perchlorate explosives. It would smolder in the laser but not actually ignite.
thank you soooo much for this video it helped me understand how vacuum chambers in facilities actually work and why mercury is used to cool down produce.
He sounds like veritasium
No i watch that channel he sounds different than this guy
what is your vacuum pump type and mark ?
Let’s put despacito in it and see if it turns in to despacito 2
Sir I think it did not froze because as Boiling Point differ at certain Pressure same will happen to the Freezing Point it will increase also instead of 0 to maybe negative something depending on ambient pressure.
Did you put a desiccant to suppress the water from getting into your pump? if you didnt R.I.P. your pump
Hi, do you know what type of vacuum pump can be used without desiccant for this experiment ? we are trying to setup this demonstration as a science project work
@@kratiagrawal6965 most can just be sure to keep an eye on the oil quality soap s not to damage it
What a good toast at the begining. Cheers
Do a test how much the vacuum chamber weight when in vacuum!
this is earth, a vacuum on the surface of earth is still affected by earth's gravity,so it should be no difference.And they also need a larger vacuum chamber for that :P
Things are different at space station or satellite is because they are not stationary, they move alot (have momentum) to counteract the gravitational pull so that they wont fall down to earth.
Point is Vacuum simply state that that space has no gas in it
Lol gravity
Since the majority of mass of the vacuum chamber is the solid walls of the container, removing the air from inside will not noticeably change its weight. This is why vacuum airships that could exist in concept, have never become a reality. It is impractical to build a lighter-than-air vessel with walls rigid enough to support the vacuum inside the vessel.
we have been using this process for herb extraction. more extracted and a lot faster with no fear of damage.
Excellent.
You just answered my two questions, does it boil, and what is the lowest temperature.
It would be interesting to see this with a different liquid, in particular a paint.
I was watching the painting of the outside of the spaceship during the opening credits of Red Dwarf, and it finally occurred to me after twenty-five years to ask: is this even possible?
Did you really questioned if does it actually boil?
@@MisterChief711 are you speaking english because it’s hard to tell, lol.
@@BLAZENYCBLACKOPS "you just answered my two questions, *does it boil?*"
This question has arbitrarily come on to my mind and I found this video on RUclips
put ballistic gel in the chamber!

it wont?
RainchenYT Rain It's just going to melt.
It wouldn't even do that.

what happens to liquid nitrogen in vacuum chamber
MOURYA SHAH most likely it'll boil faster and turn back into gas.
MOURYA SHAH it loses more energy, until the point it freezes and turn into solid, he already made that
MOURYA SHAH it would rapidly freeze.
Excellent superb 💧🌱
dose water without air in it taste any different?
RobluxMastah 214 The formula for water is 1 cell of hydrogen and 2 cells of oxygen.(At least I think I didn't check my facts) If you take the oxygen out and then drink it. It will most likely kill you.
k
Whaaaaaat?!!!...
Water with no air tastes the same!
Rednaxela Buttocks the formula is H2O so its 2 hydrogen atoms and 1 oxygen atom
Science is beautiful
Can you cook mac' cheese in it?
if you like to eat mac and cheese that isnt cooked at all then yes
Karan Randhawa spoiler... it is boiling technically, so i was just wondering
This is one smart dude. Thank you so much for this AWESOME explanation of WHY my chamber vac liquids boil
HEY!! [cant think of any funny comments rip my youtube career xD]
Manop Physics lol
Copycat alert
Hi, I am planning to heat ethanol under vacuum.
Will try to produce carbon nanotubes.
Is there an explosion risk? Air will be all vacuumed. In case of a small air leakage to vacuum chamber will it immediately explode?
Second question
After separating carbon molecules, water will also appear in the chamber. Does water vapor and Ethanol vapor create any explosion on hot surfaces above 500C degrees?
I always thought fish breathed water☹️

I think it didn't freeze because -as it is tap water- it has different things desolved in it like salt, Magnesium, etc and with the ions in it, the freezing point of it decreased, thus never freezing while boiling. Long ago, Cody from Cody's Lab did the same thing, but I believe he used destilled water and managed to freeze it.
It's called, "sublimation," which means it becomes gas but temperature always remains the same.
That's not what sublimation means. Sublimation means that something goes from the solid phase to the gas phase without ever being in the solid phase that usually is in between.
Very informative, thank u.

I thought I was gonna see the water fully evaporate, leaving behind a gooish or even dry-ish mix of what was once the food colorant, and then we'd get to see how quickly it'd turn back into liquid the moment you undid the vacuum, but I guess the water turning into vapor would forcefully be taken out of the vacuum as the mechanism does the vacuuming and it'd never come to what I was thinking xD
Cool video, I knew pressure affected the boiling and not just temperature, but I didn't know how noticeably different it'd be among locations within Earth that humans could be at xP
why say "boiling"? it doesnt heat up! should be called "bubbling"
+Neil Baxter because the definition of boiling is when the vapor pressure of the liquid is greater than the pressure surrounding the liquid. Bubbling is when there are simply bubbles of a gas in a liquid. Boiling and bubbling are completely different phenomenon.
Water in a vacuum first bubbles then boils!
Felix Rojas That's because some parts starts boiling first
So little bubbles aren't boiling but big bubbles are?
We only assosiate it with heat becuz MAC N CHEESE
trees are cool, especially redwoods. Fascinating. If there’s no heat being applied, how do trees release gaseous water in the leaves? Liquid in roots to gas in leaves. Increase pressure, decrease temperature. By that logic, trees are constantly boiling water. I guess the same logic is applied to other plants.
Hi! very interesting experiment! What do you think going to happen to the pH? the water going to loose CO2, than carbonic acid, and the pH will increase?
Best explanation
Amazing video’ thank you. You had great teachers.
Will the water all eventually boil away? Can I use this to dry liquid in electronics without damaging them?
Cool! Next time my city puts a boil water notice I'm going to put my tap water under vacuum pressure to do it B)
Hi Sir, currently I am working in a project of converting water to steam by a vacuum chamber with water coming in to the chamber and the idea is to have a pressure that a allow that water to boil straight away once is in the chamber. Any recomendations to make this happen?
Is it not dangerous to put a battery in a vacuum chamber? Especially one of the sealed button types?
You should send a balloon into space and try this experiment with water. Will it freeze or boil
Seems very logical. If you use a pressure cooker water boils at a higher temperature. So if an increase in pressure increases the boiling temp then a decrease should decrease the boiling temp.
When water boils does the atmospheric pressure become higher? Also do you have to continue vacuuming in order for the pressure to remain constant? Or can you vacuum a chamber and let it sit at that atmospheric pressure then warm up the chamber to warm up the water and let it boil at a low temperature?
the pressure will increase just enough to stop the boiling effect, yes you have to keep pulling vacuum. the water will turn to ice with a good vacuum pump. you can also heat up a bottle of water to boiling point then take it off the flames put a cork stopper. the water will stop boiling after a short time but by placing your hand on the bottle it will start to boil again. this is because you remove heat from the trapped air and it creates a vacuum in the bottle and the water boils.
the water in that last demonstration was never going to freeze until after you released the vacuum, for the same reason that it was still boiling. do you mean raising the pressure also heated the sample enough to prevent freezing?
Boiling occurs whenever the vapor pressure of the liquid and the environment pressure are equal. Evaporation occurs at all temperatures between the melting point and the boiling point, (fastest evaporation speed at boiling point)
If you stop the vacuum pump and close the vacuum in the vacuum chamber, does the boiling continue? or the pump must always work. I mean if the pressure remains at -1 bar in the vacuum chamber after the pump is stopped, but the vacuum chamber keeps the vacuum at -1 bar further.
That was really cool!
When the gases boil of from the water is there a way to collect the oxygen
Amazing explanation.
If you put ice in a vacuum chamber would it melt under vacuum and refreeze once pressure returns? May have to do this in a walk in freezer so the temperature stays freezing?
Thank you for explaining everything!
It was really helpful!
