Q. 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
Explanation
(c) At absolute temperature $T = 0 \Rightarrow v_{rms} = \sqrt{\frac{3RT}{M}} = 0$
Therefore, there is no motion of gas molecules at this temperature
