Question

According to the kinetic theory of gases, at absolute temperature

A

Water freezes

B

Liquid helium freezes

C

Molecular motion stops

D

Liquid hydrogen freezes

Answer

Molecular motion stops

Explanation

Solution

At absolute temperature $T = 0$

Ž $v_{rms} = \sqrt{\frac{3RT}{M}} = 0$

Therefore, there is no motion of gas molecules at this temperature.
