Question

At low temperature, low – lying states close to the ground energy levels are overly populated.

(a) True

(b) False

I had been asked this question in an online interview.

This interesting question is from Boltzmann Distribution topic in section Properties of High Temperature Gases of Aerodynamics

Answer 1

The correct choice is (a) True

For explanation I would say: At higher temperatures, the molecules are spread over different states in several energy levels but the same trend is not observed at lower temperatures. At temperatures below 5K, molecules are near or at the ground state thus making it overly populated.
