The ratio of most probable velocity to that of average velocity is

Which of the following gases has the highest root mean square speed $(u_{rms})$ at the given conditions?

In deriving the kinetic gas equation,use is made of the root mean square velocity of the molecules because it is

The rms velocity of oxygen molecules at $27^{\circ} C$ is around $800 \ m/s$. The rms velocity of methane molecules at $600 \ K$ temperature is around ...... (in $m/s$)
