According to the kinetic molecular theory of gases,the root mean square velocity is proportional to .......

The ratio of root mean square velocity of hydrogen at $50 \, K$ to that of nitrogen at $500 \, K$ is closest to

At $256 \ K$,the $rms$ speed of $SO_2$ gas molecules is $3.16 \times 10^2 \ ms^{-1}$. What is the most probable velocity (in $ms^{-1}$) of the same gas at the same temperature?

The ratio among most probable velocity,mean velocity and root mean square velocity is given by

At $400 \ K$,the root mean square $(rms)$ speed of a gas $X$ (molecular weight $= 40$) is equal to the most probable speed of gas $Y$ at $60 \ K$. The molecular weight of the gas $Y$ is:

The speeds of four particles are $2, 3, 4,$ and $5 \, cm/s$ respectively. What will be their $rms$ speed?
