Molecular Speeds & Maxwell Distribution

The temperature of an ideal gas is increased from 100 K to 400 K. If ' $x$ ' is the root mean square velocity of its molecules at 100 K, r.m.s. velocity becomes

Show answer and solution

Answer: (b)

$v_{rms} \propto \sqrt{T}$
$\frac{v'}{x} = \sqrt{\frac{400}{100}} = 2$
So the answer is (b) $2x$ .
