Question: In thermal equilibrium, the average velocity of gas molecules is

Options:

A) Proportional to $ \sqrt{T} $

B) Proportional to $ T^{2} $

C) Proportional to $ T^{3} $

D) Zero

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $ v _{average}=\sqrt{\frac{8RT}{\pi M}} $

Therefore $ v _{av}\propto \sqrt{T} $
