you're so very proud of your little pun in the beginning and I found that hilarious. You're a great teacher man. I've been struggling in chemistry and your videos really help me out. Thanks man!
I'm a secondary school teacher in the UK. Your videos are great - accessible, clearly explained and interesting. I use them a lot and my students really like them. Thank you - you're doing a great job!
so at absolute zero, the gas inside a balloon would have zero volume, the air wouldn't take up any space, so it would be like the balloon didn't have any air in it. if a balloon doesn't have air in it, we don't say that the balloon doesn't exist, we just say that the balloon isn't inflated, that the air inside isn't taking up any space.
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
Depends what you consider "solid". Matter that has been cooled down to almost absolute zero is actually hard to store at that temperature because it tends to pass through the matter holding it. It easily "slips" through solid glass because the cooled down molecules move so little that they don't collide with the glass molecules that much.
@rafaeldelaflor good question. did you notice that i'm using a magic balloon that doesn't burst at high temperature? also, the mass of the molecules doesn't change when it gets to absolute zero. absolute zero is a "theoretical concept," an idea that scientists think about. if you actually got it that cold, the gas would still take up a little volume because of the size of the molecules.
Gases has mass, so it is matter. At absolute zero, theoretically, all matter would be in solid phase... gases are so tiny that could take up a lot of space at room temperature, but it doesn't mean that it has no volume when it become solid at absolute zero... Probably, the Jupiter would dramatically shrink as small as the Earth's moon.
I have the same concept, gas cannot have 0 volume at absolute zero,it might decrease but it might never go to zero,because 0 volume means no matter and how can matter vanish into thin air? Thanks!
How much of a positive degree centigrade available and that much Negative degree Centigrade . Our standardisation by water based is only Zero degree centigrade ( ICE ) . In laboratory. In one bar pressure.(Atmosphere). Like the same pressure . Both are linked to a certain limit. Volume ? Water in A100 degree centigrade and pressure and volume and inject particular chemical trying or water in negative temperature above the same .
Thank you so much! I've been falling asleep watching other explanation vdos for this topic! (forcing myself to study and understand, and it just didn't make sense to me until thiss) You really pull this out very interesting!!!
So,if you have gotten a doubt like I had, then read it full. So a gas has zero volume at absolute zero but it's theoretical and practically volume can only be zero is there is no matter or mass and gas has mass,so a gas having some mass is at -272 c is not going to vanish at -272 c . Practically at absolute zero a gas does not have any motion of it's particles. But you still might be thinking if gas does not has 0 volume at absolute zero,then why they say there is 0 volume because concept of absolute zero is derived from Charles law and this law is only applicable on gasses at after a certain temp all gasses turn into liquids and solids and Charles law is not applicable on them and we cannot find the volume of a solid or liquid from Charles law so it says "the gas has zero volume" and that's correct but" there is some liquid and solid in place of it which has some volume.
Why is O Kelvin the coldest temperature possible ? They say , because at that temperature the volume of gas would be zero so it means it would have changed into liquid till that temperature than we could make the liquid further colder than that. why are we only concerned with gases???
-273C is the lowest possible temperature which would have been achieved if the substance remains in the gaseous state , but actually all gases convert into liquids above this temperature. Also, according to the video all particle motion would stop at absolute zero which means there will be zero volume of a gas at this temperature, but for a real gas zero volume is impossible (obviously) which shows that this temperature cannot be attained for a real gas.
wait did I miss that, I didn't think Tyler was selling meth in New Mexico. Ahh man he better watch out last guys who sold on Hisenbergs turf got fucked up. gonna miss his videos
This is a great 'Conventional Wisdom' explanation video - But a long question, with red shifts, ample evidence of dark energy, and arguably Van der Waal motion at 0.00K, and an apparently expanding universe!!; isn't time for physics professors to offer physics course where a central theme is: Conjecture, has 'inverted physics' been an overly neglected topic worth exploring more in 2025? Is Mary Fowler's geophysics PREM chart a primary benchmark for these type of physics classes?
So, I am definitely not a Quantum Mechanics Scientist. But I do know that if something is cold heat flows from other objects into that cold object to reach an equilibrium type deal. Wouldn't it be impossible to reach absolute zero since there will always be objects around to transfer heat into that specific area/object
Theory that any gas at absolute zero does not have any volume is theoritical and practically only the motion of the gas particles stops,because no matter can vanish in thin air,isn't it? Please correct me if I am wrong,I might gather some knowledge.
If you extrapolate the ideal gas law, yes. However, very few (if any) substances would remain in the gas phase if you brought them down to absolute zero.
"While watching this vid for the 1 st time , I was in 10 th standard ...already finished the topic the year b4 but I just realized it could have been even better if I had watched it back then" Today I m studying Astrosciences in one of the most reputed colleges in the world
The Celsius temperature would be negative, but the Kelvin temperature can never be negative. There is nothing special about zero Celsius that makes temperatures below it, behave any differently by virtue of being negative. It is an arbitrary zero point we assign using water as a reference. The Kelvin temperature is more fundamental, and its zero point matters a lot more.
How does real gases behave? Doesn't the gas in the ballon will become vapor, an time after it will become liquid? The melting temperature for hydrogen is -259. So its pretty simple for me to undestand the math concept, but the physics gets out of my mind. I beg your pardon for my english im from Colombia.
But they say they have achieved negative temperature means LOWER than 0K,........um....what does this mean? They attained the temperature lower than the possible temperature!?!....Can you please explain it? Thank You.
you can have temperature which are negative degrees kelvin but they are not colder than absolute zero... they are hotter. search for 'negative kelvin' on youtube and you will find some good videos explaining this phenomenon.
Very interesting lesson. I like the fact that you can not only make it interesting - but also funny at the same time (magic baloon). Thank you for inspiring and teaching ^^
u know what? at ab-zer0 the gas would lose it is gas- specification, and turn into a non floating dust like particles,,, in the case of gas the space between particles is huge,, due to kinetic energy,,when it is ab-zer0 it is a game changer...
Negative temperatures only exist for temperatures in relative scales like Celsius and Fahrenheit. And it just means a temperature below the temperature we arbitrarily assigned as zero, for these scales. In the case of Celsius, water's phase changes are used as a reference, so that just means a temperature where in 1 atmosphere of pressure, that the water would be solid. Negative Kelvin temperature doesn't exist. The closest we've ever achieved to it, the last time I checked, is 100 picokelvin.
It's a point where the equation is non-physical, and doesn't reflect reality. The substance would have to still be gaseous, otherwise the equation wouldn't be valid in the first place. Few (if any) substances are gaseous anywhere close to absolute zero.
Did you know that I'm working with a magic balloon?
IKR TYLER ;)
Really 🤔🤔🤔🤔
Don’t know if I can believe you there
you're so very proud of your little pun in the beginning and I found that hilarious. You're a great teacher man. I've been struggling in chemistry and your videos really help me out. Thanks man!
Daaaamn this brings back memories. I used to watch your vids when I was in high-school
Did u hear about the guy who was frozen to absolute zero? Well I heard he's 0k now.
goddamit
no
Whyyyyyyyyy
Good Pun!
Nice
Eight years and still helpful thank u for making this great explaining ❤️

Im not sure if this is a dumb question but what if we cooled down a solid like iron. The volume wouldnt hit zero so we could keep cooling it?
Will it be converted into liquid inside the baloon???

How are these 11years old and still the best chemistry videos on RUclips?!? 😂

I didn't understand anything at class and this cleared it all! thank you.
Who needs tuition classes after watching your videos ? .. Just awesome ❤
Thank you so much! It's really Very helpful ..
Conor Colburn Why what's wrong with her English?
Beside good way of teaching, I also love the rich vocabulary you use. ''Extrapolation,'' I remember you as long as I use 'extrapolation.'
How much of a positive degree centigrade available and that much Negative degree Centigrade . Our standardisation by water based is only Zero degree centigrade ( ICE ) . In laboratory. In one bar pressure.(Atmosphere). Like the same pressure . Both are linked to a certain limit. Volume ? Water in A100 degree centigrade and pressure and volume and inject particular chemical trying or water in negative temperature above the same .
Unit change to Kelvin.
Our universe is working water based.
If you want more go to another universe working parameters as you like .
Your vids are absolutely comprehensible.. Physics just became a little less complicated.
Tyler! can you please make some videos on Molecular Orbital Theory and Valence Bond Theory...would be thankful to you.. :)
Thank you so much! I've been falling asleep watching other explanation vdos for this topic! (forcing myself to study and understand, and it just didn't make sense to me until thiss) You really pull this out very interesting!!!

This was great, needed to write a paper on the history of absolute zero which was kind of hard to do until I understood absolute zero. :)
Thank you Mr. Rogers!.. I mean Tyler!
Very helpful!! ACING this presentasion
Why is O Kelvin the coldest temperature possible ? They say , because at that temperature the volume of gas would be zero so it means it would have changed into liquid till that temperature than we could make the liquid further colder than that. why are we only concerned with gases???
-273C is the lowest possible temperature which would have been achieved if the substance remains in the gaseous state , but actually all gases convert into liquids above this temperature. Also, according to the video all particle motion would stop at absolute zero which means there will be zero volume of a gas at this temperature, but for a real gas zero volume is impossible (obviously) which shows that this temperature cannot be attained for a real gas.
So theoretically if you freeze material to absolute zero, it will be volume less, thus massless, thus you can propel it at light speed.
So... if we take, say, a gas giant like Jupiter and freeze the gas to absolute zero it would vanish?
So the people living near ploes have less volume when compared to the people living near equator..
I was looking all over for this exact kind of video
Really cute but informative video. Thanks!
Thanks u sir.. Love to ur teaching from India🇮🇳
Explained it perfectly 👍
You just gain a new subscriber! :)
Man, he went against hisenberg like already in the beginning
wait did I miss that, I didn't think Tyler was selling meth in New Mexico. Ahh man he better watch out last guys who sold on Hisenbergs turf got fucked up. gonna miss his videos
Aaah..!! Love the expressions that you make while introducing ABSOLUTE ZERO !! :* ILU..!!
hi! how did you get the number that you plotted in your graph?
Thank you so much!

Thank you… I never understood it till now.
Watching 2 hours before exam 😏
Thanks for explaining in this easy way
Please make more video they help me lot
i love all your videos Tyler & i love you
Slope is [L]^3/E? The slope of He is 7/25. I'm wondering about other nobel gasses.
is there an opposite of absolute zero? thanks for making these videos!!
sir please give more about Kelvin scale
its true you should also read about nebulla boomerang
My fav teacher♥♥😭😭😭
Awesome explanation....
beautiful video
is there a connection between absolute zero and the dark matter in the universe

and im gonna fail and be the janitor in one of the most reputed colleges in the world
Tyler DeWitt and his Magic Balloon!
Thank you for this !
Very helpful,
Hey,.how come magic??
According to Charles' Law, Volume and Temperature are directly proportional. So if the temperature is 0K, then the volume is 0L
V=T
0=0
Only if it remains in the gas state. In reality, there are no substances that would remain in the gaseous state at absolute zero.
Thanks teacher for making it a piece of cake for me .. 😊😊😊
When you say Volume, Do you mean Avg. Kinetic Enery?
Otherwise even 0 Volume doesn't make sense.
So if we cool one ton of gas it will not have any volume? Where do all the atoms go?
thanks bro it helped me
If they don't move at all ...they are violating the Heisenberg's uncertainty principle bec then I can tell its momentum and position simultaneously.
what if we can achieve black holes with negative volume o.o
Should we not draw the graph in 2nd quadrant? Temperature will be negative there.....
The Celsius temperature would be negative, but the Kelvin temperature can never be negative. There is nothing special about zero Celsius that makes temperatures below it, behave any differently by virtue of being negative. It is an arbitrary zero point we assign using water as a reference. The Kelvin temperature is more fundamental, and its zero point matters a lot more.
Would gravity work on the particles of gas at absolute zero?
Yes.
So everything has to be liquidated at +273c
perfectly explained
I like the magic balloon.
I am seeing in 2020..thankss a lot
magic baloon!! lol!!
anywaz ur awesme..
tanQ 4 makin tes easier to study..
do u hav chemistry videos?
How does real gases behave? Doesn't the gas in the ballon will become vapor, an time after it will become liquid? The melting temperature for hydrogen is -259. So its pretty simple for me to undestand the math concept, but the physics gets out of my mind.

Hira Khan uh no. No one has ever gone lower than 0 Kelvin. Whatever you are reading is probably the Bible. Just stop.
you can have temperature which are negative degrees kelvin but they are not colder than absolute zero... they are hotter.
search for 'negative kelvin' on youtube and you will find some good videos explaining this phenomenon.
Thanks a lot!! helped me do my Project and thanks for making me Pass!!
thank you
Very interesting lesson. I like the fact that you can not only make it interesting - but also funny at the same time (magic baloon). Thank you for inspiring and teaching ^^
you helped me paass Ty bro
13yrs ago now
Thank you soo much
incredible
u know what? at ab-zer0 the gas would lose it is gas- specification, and turn into a non floating dust like particles,,, in the case of gas the space between particles is huge,, due to kinetic energy,,when it is ab-zer0 it is a game changer...
Thanks for this my physics teacher shames me and makes fun of me for not understanding but know I understand thanks alot
The molecules have absolutely no mass at absolute zero? How can it have no volume when it has mass? And if your balloon would blow up way before 200
@managarm1349 That doesn't mean it isn't possible though :)
Very nice ..
If having a negative volume for a gas is so ridiculous, isn't having a zero volume as ridiculous?
So helpful....
0:09 correction * 273.15 degrees celsius* but thx XD
Thanks Alot ...
Thanks man!
Still not as cold as my ex-wife.
BURN
Cold burn?
DRY ICE BURN
XDDDD love it!
+Miso_Soup!Go hahaa
i felt so cold whenever he said absolute zero
I wish my teacher used a magic balloon so that I memorize all these gas stuff magically
Then what is negative temperature.
Negative temperatures only exist for temperatures in relative scales like Celsius and Fahrenheit. And it just means a temperature below the temperature we arbitrarily assigned as zero, for these scales. In the case of Celsius, water's phase changes are used as a reference, so that just means a temperature where in 1 atmosphere of pressure, that the water would be solid.

Please Tell Something about the MAGIC BALLOON :D
nice reply sir
thank you so so so so so so much ❤️❤️❤️❤️❤️
THANK YOU IM SO HAPPY AND I LOVE SCIENCE AND I JUST LOVE THE PROCESS OF UNDERSTANDING WHICH WAS POSSIBLE NOW BECAUSE OF THIS AMAZING EXPLANATION
Thanx
how volume can be zero? donnot understand well
It's a point where the equation is non-physical, and doesn't reflect reality. The substance would have to still be gaseous, otherwise the equation wouldn't be valid in the first place. Few (if any) substances are gaseous anywhere close to absolute zero.
I need a magic balloon too😂😂😂
