Answer 1

The RMS speed of the gas is given by:

v

rms

=

M

3RT

It means that the RMS speed is inversely proportional to the molecular mass. Therefore, the gas with lowest molecular mass will have maximum RMS speed.

Hydrogen has the lowest molecular mass as compared to other gases. So, it will have maximum RMS speed.
