Low temperature

  1. Dec 25, 2011 #1
    i learnt that we have to consider quantum effects at low temperatures and classical effects at high temperatures but i do not the physics behind it
    can anyone explain it for me??????????
    thanks in advance :)

    Very roughly, Bohr's correspondence principle says that in the limit of high quantum numbers, classical physics applies.
    And at low temperatures, only states with low quantum numbers are occupied.
