Molecular Speeds & Maxwell Distribution

When the r.m.s. velocity of a gas is denoted by ' $v$ ' at temperature ' $T$ '. Out of the following relations, the true one is

Show answer and solution

Answer: (d)

$v_{rms} = \sqrt{\frac{3RT}{M}}$ , so $v^2 = \frac{3R}{M}T$ .
For a given gas $\frac{3R}{M}$ is fixed, so $v^2 \propto T$ .
So the answer is (d) $\frac{v^2}{T} =$ constant.
