Molecular Speeds & Maxwell Distribution

If ' $m$ ' represents the mass of each molecule of a gas and ' $T$ ' its absolute temperature respectively, then the root mean square velocity of the gaseous molecule is proportional to

Show answer and solution

Answer: (b)

$v_{rms} = \sqrt{\frac{3k_BT}{m}}$
So $v_{rms} \propto m^{-1/2}T^{1/2}$ .
So the answer is (b) $m^{-1/2}T^{1/2}$ .
