Will a matter get 0 volume on -273 C?

  1. Today in my chemistry class, the teacher said:

    Is it true? If yes I have a doubt. 0 vloume means the matter will demolish right? Then how will the mass of the demolished matter be conserved according to Law of conservation of mass?

    This is not true.
    Also note that a full Bose-Einstein condensate is the lowest-energy state (for bosons), it is at 0 K and you cannot make it cooler.
  4. Do you mean the lowest possible temperature a matter can be cooled is 0 k?

    That's the definition of 0 K, yes.

    There is a good reason to assign negative temperature values to some systems, but those are hotter than any system with zero or positive temperature.
  6. There are some very interesting properties of a Bose-Einstein Condensate (BEC)...

    Yes, they were just not detected. If you had read the Wikipedia entry, you would have seen after twhat OCR quoted:
    Also, the statement
    is mostly false. When a substance is cooled [Edit: to a low enough temperature], it forms a solid [Edit: with the exception of helium, which becomes superfluid]. Only in very special cases, such as for dilute gases, does a bunch of bosons can be coerced to form a BEC. It is not trivial to do!

  8. thank you DrClaude
  9. Could a real rate of matter volume become infinitely small? If you are convinced it cannot be done in the universe, then the absolute zero cannot be achieved in the universe.

    Also a demolition of the matter in 0 volume, as a real phenomenon, makes no sense to consider.
