    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.

    @EvilTim1911 12 лет назад +1

    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.

  • @tdewitt451
    @tdewitt451  13 лет назад +2

    @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.

  • @marlonangeles3085
    @marlonangeles3085 6 лет назад +3

    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.

    • @sumanjaiswal4956
      @sumanjaiswal4956 5 лет назад

      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 .

  • @sumanjaiswal4956
    @sumanjaiswal4956 5 лет назад

    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.

    @sherazkhan2802 8 лет назад +3

    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???

    • @jannatzeeshan9769
      @jannatzeeshan9769 7 лет назад

      -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.

  • @prabhatus

    So theoretically if you freeze material to absolute zero, it will be volume less, thus massless, thus you can propel it at light speed.

    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?

  • @austinbitzer9638
    @austinbitzer9638 7 лет назад

    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

  • @sumanjaiswal4956
    @sumanjaiswal4956 5 лет назад

    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.

    • @carultch
      @carultch 2 года назад

      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.

    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.

    • @carultch
      @carultch 2 года назад

      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.

    • @carultch
      @carultch 2 года назад

      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.
