The $rms$ velocity of a gas depends upon

At $3 \text{ atm}$ pressure,the weight of $14.8 \text{ L}$ of a gas is $15 \text{ g}$. What is the average speed of the gas molecules?

If the $RMS$ velocity of an ideal gas is $v \ ms^{-1}$ at $127^{\circ} C$,at what temperature its $RMS$ velocity is doubled (in $K$)?

Explain the relationship between different types of molecular speeds.

If the kinetic energy of $O_2$ gas is $4.0 \ kJ \ mol^{-1}$,its $RMS$ speed in $cm \ s^{-1}$ is

The $rms$ velocity of molecules of a gas of density $4 \ kg \ m^{-3}$ and pressure $1.2 \times 10^{5} \ Nm^{-2}$ is (in $ms^{-1}$)
