The ratio between the root mean square velocity of $H_2$ at $50 \ K$ and that of $O_2$ at $800 \ K$ is

If the temperature of a gas is increased from $27\,^oC$ to $927\,^oC$,what will be the change in its $rms$ speed?

At what temperature and $1 \ atm$ pressure will the root mean square speed of $N_2$ gas be equal to the root mean square speed of $CO_2$ gas at $STP$?

When the temperature of a gas is increased from $30^{\circ} C$ to $930^{\circ} C$,the root mean square speed of the gas would

What change occurs in the velocity distribution graph when the temperature is increased?

If the kinetic energy and $RMS$ speed of a gas at a certain temperature are $4.0 \ kJ \ mol^{-1}$ and $5.0 \times 10^4 \ cm \ s^{-1}$,respectively,the molecular weight of the gas is:
