low temperature

Muneer QAU

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.
