You can find absolute zero experimentally by taking a fixed amount of gas and measuring it's volume at different temperatures while keeping the pressure fixed. It makes use of the ideal gas law (pv=nRT) or Charles's Law.

1) OK, so I didn't know there was such a thing as "absolute hot" or Plank Temperature. Interesting!
2) There's a typo in the footnote. It should read "trippple point of watter".

Just an FYI, there is a maximum temperature.
The first one is when an atom can't hold electrons on, we call that a plasma, but we usually consider this fine.
The next is when the atom shakes so hard, there is so much energy in it, that the atoms fall apart into a proton-neutron 'soup'. This is a real absolute limit (they aren't atoms anymore).
The next after *that* is when so much energy is in there, the protons and neutrons fall apart into just quarks, making a quark-gluon plasma.
YES, Celsius

Since I'm studying thermodynamics, it was a really interesting video for me, thank you !
As soon as you went for a liquid seal, my immediate thought was that vapor from the liquid would really mess things up. Glad that hypothesis was true.
Experiments like this, where you put yourself in the shoes of a cutting edge researcher, really puts into perspective how much effort and confusion scientists and researchers in the past went through in order to find out what many nowadays regard as just numbers we can look up. If this doesn't put a perspective on the phrase "taken for granted", I don't know what will. Well, other than food, water and electricity of course...
Your videos are more engaging than Brian Cox's high production value documentaries. Somehow you always manage to find more interesting science in your kitchen than he does in the entire universe. It's amazing that you can take such an apparently simple concept, expose its subtleties, explain them, and then illustrate them with an experiment, all in the space of 15 minutes!
It's good because being shown something that you can replicate yourself in your own home makes the information seem much more accessible and credible.
When trying to work something out, it's always nice if someone has done it before you, and better.
That's a mood right there.
Using a glass syringe with a spinning glass plunger reduces the friction of the plunger to near zero giving even more accurate results. Good job. Very enlightening. Keep up the good work.
Props for including the bad result from the first experiment. It's good for people to realize how hard it is to do accurate experiments.
You already said this in your pin, but in case anyone missed that, there is actually a theoretical limit to how hot things can get.

More likely it's the hurdle of fanatic nationalism, even though we didn't invent this system. You'd think that sort of person would have more in common with a tea-dumping patriot, and distance themselves from the European-created Fahrenheit and the English-invented foot and mile and gallon and cup.

@@ericchambers9023 Given Steve's all-round practical capabilities, he'd have no trouble growing himself some pukka ganja.
We did that in physics class by heating a sealed tube with a pressure sensor and a thermometer at one end. Based on the linear relationship between temperature and pressure, we were able to find absolute zero as the zero of the linear regression of our datapoints.
Do you recall how accurate were the results?
@@dmitriiemelianenko8531 I think we had something like -271°C. Still not that accurate but far better than this approach.
So what you did was an isochoric process instead of the isobaric process as shown here.
Did you use something like nitrogen to make sure you didn't get any condensation on the cold end? That should improve the accuracy.
"because im an arseho-" lmao
Hey Steve, in your second experiment, one possible reason for the lower value (apart from measurement errors and the piston friction) might be the humidity in the air in the tube, since you used room air that has humidity that will condense at freezing temperatures, leading to lower temperature derived for absolute zero
Something just hit me. You said that the reason we can heat something indefinitely is due to temperature being a function of the speed the atoms jiggle in. So, isn't
there a limit for this speed? Can the atoms, in theory, jiggle faster than the speed of light?
I just had the axact same tought
Vsauce has a video called “How hot can it get?” in which he talks about an absolute hot. There’s actually a temperature, called the Planck temperature, at which the wavelength of the thermal radiation an object gives off would be shorter than the Planck length. So there has to be an absolute hot. If i recall correctly, tho, this would take more energy than we know of in the universe, and of course the atoms would dissolve into their fundamental particles at energies like that.
The temperature actually depends on the kinetic energy of the jiggle, not just the speed. If the atoms were to jiggle at the speed of light then the energy (and thus the temperature) would become infinite.
We can keep on increasing the temperature because we can get the atoms to jiggle closer and closer to the speed of light, but never reaching it.
Also quantum mechanics does put a limit on maximum temperature but that's a different matter
They are not longer atoms after a point.
Now, if they keep mass, that means the more you heat the sample the harder is to make it hotter.
My thought was along these lines:
Eventually you are going to cause those atoms to 'jiggle' themselves apart!
Super-colliders produce temperatures close to 10 trillion degrees for a reason....
If centigrade is anything with 100 gradations between freezing and boiling points of water, then Kelvin is centigrade too, isn't it? :)
Good point!
Yep, by definition it’s based on the centigrade scale. It’s the centigrade scale adjusted so zero is absolute zero not the freezing point of water. That’s all it is .
Yup... It's just a shifted Kelvin scale
I loved the gradual improvement to experimental setup and the reminder that Physics is not equations in a book, but reality and what's happening right in front of our eyes. But at the same time, subject to all the failures and variation of doing things for real.
I would have also tried to dither the syringe, pluck it and push it to get the upper and lower bound of the "stickiness" of the syringe, or tried to do the liquid volume calculator with a non-volatile liquid like mercury
chromostereopsis might be a fun thing to do a video on. Its an optical illusion created by red and blue colours (and green to some extent) near each other, it looks like red colours float on top on the blue colours by quite a bit. Really cool 3D effect.
Its caused by the refraction of light changing depending on wavelength, so they appear to be in different positions. The effect only works with both eyes, closing one stops it. Looks so cool aswell.
Idea for a Video:
You can show the difference of light speeds in different mediums and the therefore changing angle of refraction by the colour change of demirorred glasses in water (orange, red) in contrast to air (green).
Worked with every demirrored glasses I tried so far and makes a visually interesting effect since the reflected colour of the white light changes.
Come on brain, he typed: "de mirrored" glasses not "demi rorred". Get it right.
Ok, what are demirorred glasses? The google doesn't help.
I haven't heard of de-mirrored glasses either
When you wear glasses and the sun would be sort of behind you, the light would reflect and you couldn't see, because you would be blinded sort of. (English isnt my first language, I am sorry)
Therefore to prevent this glasses are often coated several layers of some material, which prevents this.
In german we call it "entspiegelte Brillengläser"
You can notice this trough a slight green glare or reflection from the glasses.
In my physics A-level we learned sort of how this worked. The layer reflects some light and lets the other pass trough. The light wich passed trough will be reflected in the layer below and then shine out of the glasses again. The trick is to make the layer just thick enough so that the lightwave is shifted half a wavelength and therefore cancels out with the light which reflected at the first layer.
This is of course a simplification, but it works and can eaven be used to explain the effect I mentioned. Because the light is refracted at an angle you can calculate how thick the layer should be, but when you put the glasses into water the angle changes, since it is dependent on the lightspeeds of the two media.
So the angle changes, therefore the way and length the light passes trough the layer changes. Therefore now the orange wavelengths who cancelled out earlier are now visible and the green is not visible anymore.
Maybe the english word is anti-reflective glasses
The captions from 15:43 onwards make it 10x funnier than it already is 😂
Thanks a lot for the impressive and thorough explanation Steve! I will surely need to come back several times to this video again. One question though: could one reason for the discrepancy in the absolute temperature value in the syringe experiment be related actually to the assumptions of the ideal gas law, which you used for the estimate? I remember that one assumption for the ideal gas law is that there are no interactions among the gas molecules in space. We know that this is not really the case though. As a result, the ideal gas law works best at relatively high temperatures and low pressures, at which the interactions between the gas molecules are the lowest. Hence, Could using the ideal gas when measuring the temperature of the vodka in the cold bath have contributed to the underestimation of the value of absolute zero? Your insight is highly appreciated. Thanks a lot!
"...well not the farenhet, that's stupid..." 🤣🤣🤣 You made me giggle my good sir!
Correct me if I'm wrong, please but I don't think you can increase temperature indefinitely. If the hotter body emits shorter electromagnetic waves then you hit the Planck length of the wavelength at some point or the Planck time of the wave period. And that limits the maximum energy of the body.
What you are describing is the plank temperature at 1.416785(16)×1032 K. We don't know that it is impossible for an object to be hotter, our understanding of physics just ceases to function.
@@vincentbensch7164, thanks for answering. That makes sense.
It is also possible that the black body radiation equation we know and love is incomplete..A bit like the Newtonian physics before Einstein. It is a good enough approximation at low temperatures ("low" compared to Plank temperature, that is), but may need a correction at higher temperatures, sort of like Newton's equations need a correction at relativistic speeds. Based on what the correction is, the "absolute hot" may be nowhere near the Plank temperature. It may even be infinity.

@@RicardoMontania no its not
One of the only reasons people hate Fahrenheit is because while in Celsius water freezes at 0, it freezes at 32 in Fahrenheit. However, if we were to just adjust the Fahrenheit scale by lowering it by 32 degrees, which we already do when we convert from Fahrenheit to Celsius, then that eliminates the issue most people have with Fahrenheit, giving us an Improved Fahrenheit scale where water freezes at 0 degrees and boils at 180 degrees. And since 9 Fahrenheit degrees are equal to 5 Celsius degrees, with this Improved Fahrenheit scale we can get finer temperature gradients like the regular Fahrenheit scale with a more consistent freezing and boiling point like Celsius.
@@Gakulon Why do we want a scale that is based on the freezing temperature of a solution of brine made from equal parts of ice, water and a salt (ammonium chloride)? why not just use decimal points in the centigrade scale? I find that to be a way better solution.

Improve the experiment by adding a pressure gauge to the syringe. You can adjust the plunger to adjust the internal pressure to atmospheric pressure before taking a volume reading. Thus eliminating the error because of friction of the plunger against the walls.

Congratulations.
I have a question! So how come on glaciers you can find ice much stronger and packed together. From the freezing point of 0c and then the weight of the snow on top. So actually you can get the athoms way more packed together! Right?

Thank you again an really hope I get your reply on this ☺️

2:17 - Strictly speaking, the man's name was Celsius (not Celcius - and the other man's name was Planck, not Plank). Also, 0 was the boiling point while 100 was the freezing point (yes, Celsius's original centigrade scale went the opposite way).
Also, molecules still "jiggle" at absolute zero. It's called zero point energy (and is why helium never freezes, for example, and just becomes silly instead).
Isn't there a theoretical max temperature named "Absolute hot
" or Plank temp?
Yesi think soo too. commented this too.
@@lurji lol @ don't count on it.
@@frozensakura9307 no there isn't? All planck units just unites that set the 5 fundamental constants to 1. There is nothing inherent about them that means they are somehow the "biggest" or "smallest" units possible.
Before you start, yes, when something is at planck's temp, its black body radiation will have the wavelength of 1 planck unit, but now you still need to explain how the planck length is somehow the smallest unit in the universe.
Some random trivia: The charge of an electron is called an elementary charge, it's useful because most things have a whole multiple of that charge (quarks can have some 1/3 electron charge apparently, so most). The planck charge is over 70k electron charges. Are you disappointed by planck units yet?

Awesome!
You could have used a method analogous to that used by machinists in zeroing out backlash with the syringe. Before measuring, compress the volume and let it normalize; that should mean that the pressure is constant at each measurement since the static friction should be close to constant (assuming you don't get cold enough to drastically affect your lubricant and seal) and the pressure area is constant.

"So Magnus plays 1.e4 and it was in this position that the opponent resigned"
1:20 Hah instatnt like
Steve, Another interesting and easy way to extrapolate to absolute zero is to measure the electrical resistance of metals, which is generally proportional to absolute temperature. For ductile metals without many defects, like platinum, the linearity is rather good. They are about as "ideal" resistors as gases are "ideal" gases. So, if I put a platinum wire in ice water (in fact, I can use a platinum RTD made for this purpose) I measure 100.0 ohms, and if I then place it in boiling water I get 138.5 ohms. That gives an absolute zero of -100*100/(138.5-100) = -259.7C Not great, but as good or better than trying to measure gas volume ratios!

In the 1st experiment, the constant a cannot be a constant because the pressure in the container you are cooling also changes. Namely, in the beginning you have atmospheric pressure, then you cool the container and you pour the vodka into the container, before the new pressure p1+hydrostatic pressure (ŕgh) becomes equal to atmospheric pressure. This is how I understood the setup of the experiment, I apologize if I misunderstood.

great video! I was so confuse about this too
A possible way to deal with friction in the syringe: Use a force meter to pull the syringe with a set number of newtons, release, and record the volume. Then push it with the same number of newtons, release, and record the volume. The average of the two readings should be a more accurate measure of the real volume at 1 atm. Or even possibly do the same but record the volumes when pushing and pulling.
I’m always left with an absolute zero in my bottle of vodka...

Not a lot of CZcamsrs actually do a “formal” experiment like this. Usually I’d find doing this type of thing tedious and boring, but this was so cool! Thanks!
This should be shown in schools!!.. I had a physic teacher that did similar non unit demonstrations and learnt heaps!!..
i like that you showed how far the first result was. pura vida.
14:18 so we could call that a "Parker experiment"?
You claim that you can heat something indefinitely, but if you heat a substance too much then theoretically it would collapse into a black hole (Kugelblitz)
A Kugelblitz is not a black hole! But you are right it can collapse in one
@@martinkasse1932 actually I'm pretty sure it is
@@martinkasse1932 Isn't it?
They're both regions of space behind a singularity caused by a density of mass-energy?
A Kugelblitz is a singularity originally formed by radiant energy concentrated in a small region. Presumably, any single object radiating such energy would itself form a singularity _long_ before its radiated energy did so.
The little preview-gif of this video, where he's talking, and the word vodka in the title, makes an excellent companionship :)
I love ❤️ the idea that that you did a so bad experiment to prove that you can get a "fair enough" approximation of something or at least learn something in the process of failure
