Temperature is a quantities which denotes a value which gives the average kinetic energy of molecules in a gas. This depends on velocities of gas molecules and vice-versa. If temperature does not change Vr, m . s will also not change.

Q. The r.m.s. speed of the molecules of enclosed gas is $V$ . What will be the r.m.s. speed if pressure is doubled keeping the temperature same?

$\frac{V}{2}$

$V$

$2 V$

$4 V$
