    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.

      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.

    • @ericvilas
      @ericvilas 3 роки тому +78

      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

    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).

      @mr3sepz 3 роки тому +8

      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.

      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.

    Correct me if I'm wrong, please but I don't think you can increase temperature indefinitely.

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.

    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!

      Technically the USA is actually metric, it’s just that most of the USA hasn’t implemented it. The signed on to the SI unit treaty, and NASA and several other government agencies use metric. It’s only the general population and things intended for them that are still Imperial (this includes Fahrenheit)

      It's too much of a hassle. The cost is greater than the benefit of switching. They tried it decades ago. It would certainly be even harder now.
      Don't worry, when we start a new civilization on the Moon or Mars, I'm sure they'll use Metric.

      Multiple failures at the National Aeronautical and Space Administration have already occurred due solely to mismanaged metric conversions and notations.

    Not a lot of UA-camrs 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!

    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!
