At $T \ K$,the $RMS$ velocity of $He$ is equal to the $RMS$ velocity of $SO_2$ at $127^{\circ} C$. What is $T$ (in $K$)?

The volumes of ozone and chlorine gas diffusing in the same time are $35 \ mL$ and $29 \ mL$ respectively. If the molar mass of chlorine is $71$,calculate the molar mass of ozone. (in $.7$)

At the same temperature,the root mean square velocities of two gases are $v_1$ and $v_2$,and their molar masses are $m_1$ and $m_2$ respectively. Which of the following relations is correct?

The temperature of the gas is raised from $27\,^oC$ to $927\,^oC$. The root mean square velocity is:

The relationship among most probable velocity,average velocity,and root mean square velocity is respectively:

At what temperature (in $K$) is the $rms$ velocity of $SO_2$ molecules equal to the $rms$ velocity of $O_2$ molecules at $27^{\circ} C$?
