Molecular Speeds & Maxwell Distribution

For a particular ideal gas which of the following graphs represents the variation of mean squared velocity of the gas molecules with temperature?

Show answer and solution

Answer: (c)

$\overline{v^2} = \frac{3kT}{m}$
For a given gas $\frac{3k}{m}$ is constant, so $\overline{v^2} \propto T$ .
The graph is a straight line through the origin.
So the answer is (c).
