The root mean square velocity of a gas molecule is proportional to:

Select the correct order of molecular speeds for a gas.

The density ratio of $O_2$ and $H_2$ is $16 : 1$. The ratio of their $V_{rms}$ is

The density of a gas at $100 \, kPa$ pressure is $0.1 \, g \, cm^{-3}$. What will be its $rms$ speed in $m \, s^{-1}$?

At $STP$,write the order of root mean square speed $(u_{rms})$ for the molecules $H_2, N_2, O_2$,and $HBr$.

The $rms$ speed of $N_2$ molecules in a gas is $v$. If the temperature is doubled and the nitrogen molecules dissociate into nitrogen atoms,the $rms$ speed becomes
