This is how we remove moisture from the inside of a refrigeration system or HVAC system. Solid ice will eventually sublimate away but the process is very slow. Also, water that sits under the oil in a compressor is very difficult to remove.
" Boil doesn't mean hot " " Boil ... to make bubbles rise from the liquid contents " Lowering the pressure , creates a " Lower Boiling Point " When people say the water is " Boiling " we automatically associate it with the water being hot because we are taught Boiling at normal atmosphere means " Bolling Hot " I hope this helps peoples understanding
I remember a story of some mountain climbers trying to boil potatoes, they said they was boiling them for hours but they was not cooking because the boiling temperature was too low at high altitude.
It's like the amount of atmosphere you have at a certain altitude that can compress other objects' atoms, so it's tougher for them to escape their molecular bonds at sea level than on a plane because quite literally its being held more together. It's the same reason why the hydrothermal vents at the bottom of the ocean boil many times hotter (~400°C/750°F) than at our level (100°C/212°F) because so much more energy is needed to escape the pressure of all of the saltwater water molecules bearing down on it so heavily.
boiling it doesnt mean its becoming a gas. just because water starts both really quickly evaporating and boiling at 100C degrees in a normal air pressure doesnt mean boiling water means also evaporating it. it just takes out the air from the water by vacuming it rather than heating. but you should also know that water does become gas in any temperature, so theres indeed 3 states of water here. you just can't see it because the percentage of evaporation is really small at a low temperature. comparing forzen solid, a liquid and a boiling state is confusing because boiling has nothing to do with the 2.
Fun fact there are sailboats that use things called foils which are wings under water used to generate lift and lift the hull out of the water to reduce drag. Foils are crazy efficient compared to displacement hulls their main limit on speed is they get going fast enough that the low pressure zone on the top of the wing is so low the water boils and causes cavitation, making the boat lose stability
interesting from point of wording and vocabulary. Boiling is considered as hot, though it becomes so relative and very logic when you remove unnecessary HOT condition. Similar apparent confusions happen with power and torque when daily understanding of verbal terms are not how physics works. Very nice video.
To my understanding, water boils at low temperatures im the vacuum because the lack of atmospheric pressure makes the very little caloric energy contained within each water molecule enough to make them become a gas, essentially a highly mobile molecule. At atmospheric pressure, administering the energy that is reached at 100 celsius is required for the molecules to beat the pressure forces and become a gas.
@@INTEGRALPHYSICS Sometimes many find it Ice Cold, others Liquid in Motion, and the rest at Boiling Point... but all of us will be hit unpredictably in the end.😅😅😅
Temperature at which the vapour pressure of liquid is equal to the outer pressure is called boiling point Here there is approx 0 external pressure so the boiling point is decreased to nearly 0 deg C
It's not 0, but pretty low compared to atmospheric pressure. If you got it much lower than this pressure, then you would have sublimating water ice at an even lower temperature than the typical melting point

Heey thank you for answering my decade long question! Back when I studied at lyceum my physics teacher told us the boiling temperature varies depending on the air pressure. So I asked if we keep decreasing the pressure can we boil water at 0°C and she couldn't really answer me that time. But now I know!
The big misconception that's hard to get past here is that boiling does not equal hot. The water is not hot, it is at the freezing point. That's why I stuck my finger in the water at the end; It's ice cold. You aren't going to cook anything in there.
@INTEGRALPHYSICS so, the water is just turning into gas because there's nothing squeezing it together. While when it gets hot it's too excited to be squeezed together. How much atmospheric pressure is needed to keep water from boiling at any temperature?
I see this a lot when distilling at work. I thought it was just the vapors being sucked out so hard that it’s starts to pull the liquid. I didn’t know they where heat bubbles.
Maybe at first, but air isn't very soluble in water, so that will soon be exhausted and you will get water vapour boiling off from the surface, followed by the water freezing. The triple point is at around 6millibar or just under 0.1psi. That's designated a 'rough vacuum', and not too hard to reach with a decent pump.
The triple point of water is 0.01°C 611.73 Pa, so the boiling point came down 99.99°C while the freezing point rose only 0.01°C as we pumped down from 101,325 Pa (or slightly less depending on elevation and or even more depending on HVAC).
U can fill the syringe with some water, plug it with your finger and pull out the air. It boils water in it. (!!!) it won't rid the water of harmful bacterias
You can also make a one way valve using 2 syringes and a modified jar to make it boil, that is if you don't have a vacuum pump. The syringe is really great too. You can also try rubbing alcohol because it has a lower boiling point than water it will boil more easily.
Boiling dosen't mean to heat something it means that you are changing the state of the matter form liquid to gas like you do in your home by taking heat as a medium but in this video he is using pressure as medium...
Sadly most of the water was still above 0.01 °C. I'd start with only water, so that you can see ice directly sublimating (That's how freeze dryers work btw.). And I don't think your vacuum pump reached the triple point at 6 mbar (and 0.01 °C). Or even cooler: You can freeze water by boiling it :D When you put water in a vacuum, it starts boiling. Since boiling needs energy, it will take that from its surrounding, cooling the water down until it freezes.
Here's the short of the water cooling as state change occurs... ruclips.net/user/shortso5jcEjEbmuo I made a recording of starting with room temperature water and cooling it in the vacuum until it froze but it took a few minutes and wasn't the most visually entertaining event. (ie. it didnt make a good short)
also, the water at the top tends to steal some of the energy from the main body of water as it boils away - reason why you feel colder as sweat evaporates off you, or why the average water temperature can decrease if the sun starts shining on a body of water
This is such a great demonstration, it’s pretty cool that we can reach the triple point for water without incredibly fancy instruments
Thanks! It is surprising more people don't do it as a demo in chem and physics classes.
I never really understood the triple point before this
What gas is released from water - in this experiment?
@@inwithsliminwithjim3416 Water. It’s boiling, so it’s just like when you boil water on a stove and it “releases” water in the form of steam.
@@xilorphone Ok, I was wondering it it could be developed into a way of creating fuel from the hydrogen/oxygen - thank you.
I feel like if that water could talk, it would be uncontrollably confused screaming.
😂😂😂😂😂😂😂😂😂😂😂😂😂😂
I feel like if I drink that water, I'd somehow become super human 😆

WAAAAHThank you very much. This is very helpful.
And I thought I had to much time on my hands...
nice job👍👍👍
Thanks, it was much needed 👏
so if someone was to touch the beaker it would be cold right?
This is how we remove moisture from the inside of a refrigeration system or HVAC system. Solid ice will eventually sublimate away but the process is very slow. Also, water that sits under the oil in a compressor is very difficult to remove.
" Boil doesn't mean hot "
" Boil ... to make bubbles rise from the liquid contents "
Lowering the pressure , creates a " Lower Boiling Point "
When people say the water is " Boiling " we automatically associate it with the water being hot because we are taught Boiling at normal atmosphere means " Bolling Hot "
I hope this helps peoples understanding
Makes sense
Boils means going from liquid state to gas state
@@arjanjansen1829 that's evaporation.
@@kenpinbasar2531 that is not evaporation.evaporation is changing of liquid to gas state occuring at only surface of liquid.
WoW that's nice
They is absolutely bonkers. I love information like this, almost makes co-rotating magnetic discs creating an anti-gravity field make sense..
Learning indeed becomes fun when we have such wonderful teachers around us demonstrating experiments.
Woow you explaining why water boils in the outer space or vacuum is the best explanation I've ever heard
Using the rules to break the rules is a wonderful concept that you displayed perfectly. Can't wait to see the devs patch this out in the next update.
I remember doing this triple point experiment over 46 years ago in Highschool Chemistry class and its still an amazing process.
I remember a story of some mountain climbers trying to boil potatoes, they said they was boiling them for hours but they was not cooking because the boiling temperature was too low at high altitude.
This is the best explanation of triple point of water. I am glad that i come across this video. 😅
Glad it was helpful!
That’s the exact state my body goes into when I walk into a spider web

Seeing triple point in chemistry books is nothing like seeing the triple point reached here. Awesome demonstration thanks
Wow I never understood how the atmosphere affects boiling points till I watched this lol, now it all makes sense
You are the only one who could explain it to me.....

Damn. I thought I was going to have to call out another “science” video but this all checks out. Good job.

Now we sure believe in frozen hell
Vacuum - the place where water has superpowers
Why could my teachers not be this engaging? I excelled in science and math in school. Luckily it came naturally to me.
perhaps you could become one now!

Similar apparent confusions happen with power and torque when daily understanding of verbal terms are not how physics works. Very nice video.
This is actually so cool
Water: wait a minute, am I supposed to be boiling or melting now?
And this is why you don’t take off your spacesuit in space!

This is the first time I understood the triple point.
Penny drops!.... always wondered why your blood is supposed to boil in the vacuum of space when exposed to a decompression
🪙⬇️🤣
The triple point of water is one of the two defining points of the Kelvin scale, at precisely 273.16K. The other point, of course, is absolute zero.
I will forever love chemistry, the mother of all human illusions
Bravo my man, great way to show the triple point!
Quite a few of those bubbles were probably air from the melting ice, but I think it was boiling too.
my girlfriend hovers at this triple point most of the time....
now i know how, thank you!
LOL

I cannot find this in the comments:

Good job with the experiment, too! :)
I love that shirt.
Thanks sir
When I read this concept and googled the images, I didn't get satisfying results. But u demonstrate it in v good manner
Totally changed my life
Here in Albuquerque where much of the city lies a mile above a mile msl, water boils somewhat less than 212 F, or 100 C.
where i live water boils at 7000C
Great for saving energy! I can boil water and my Rahmen noodles without turning on the stove. Thanks!
It will not cook any thing , it same like we can't properly cook seeds/pulses in mountain areas
@@freel0077 whoa! So you can't cook there!? Since boiling point is not hot enough?
@@strangerfable8666 yes it is abt 7 to 15 C less in Gilgit baltistan area due to low atmospheric pressure.

There's nothing hot here. Its just water vapor.
A Água não mente ! Sistema fechado, PLANO e estacionário. 😍😍😍😍
It is not so easy to obtain a perfect vacuum and the triple point. The bubles in the clip contain air, not water vapor.
Maybe at first, but air isn't very soluble in water, so that will soon be exhausted and you will get water vapour boiling off from the surface, followed by the water freezing. The triple point is at around 6millibar or just under 0.1psi. That's designated a 'rough vacuum', and not too hard to reach with a decent pump.
Basically like Mars
Oh baby, it's triple.
That's cool ... 👍
interesting ...
thank you for sharing
Water was so confused 🌬️🔥
The triple point of water is 0.01°C 611.73 Pa, so the boiling point came down 99.99°C while the freezing point rose only 0.01°C as we pumped down from 101,325 Pa (or slightly less depending on elevation and or even more depending on HVAC).
triple point
I remember studying it at school and it was counterintuitive! :)
Well done
I appreciate the mystery of the universe, but this seems like something I should be able to rationalize. Back to mystery 😃
thats would taste like heaven water
in vacuum the water really want to fill that empty space.
I wish they could explained to me like this when I was at school
Water is nuts
And people think we live on a ball, floating in space, in a vacuum
I knew I could cook some nice chocolate ice
You guys will get it.,
When you know PV curve or Cooling curve in thermodynamics.

Have learned it; never seen it. Like so much physics it can get quite counter-intuitive.

We also have something called NTP, coz properties of elements will change as per pressure and Temperature
Hmm,so pressure is the reason why it is difficult for people at higher altitudes to cook vegetables as water starts boiling at lower temperatures
its same as stuffs in outer space. its cold n vacuumed at same time.
That is very cool!
Yet another reason for me not to go to space
Carbonation folks, clear liquid is a color and dyeable

See,how easy to understand it this way,i don't know why the fuck i used to read in those books
That was crazy 💀
I think you can spare energy desalinating sea water this way.
Presumably the higher energy molecules are the ones leaving as a gas and so there will always be some temperature gradient?
So basically, you'll simulateously boil and freeze in space.
I've always wondered that🤯
