The root mean square velocity of an ideal gas at constant pressure varies with density $(d)$ as:

Which of the following is a way to decrease the average speed of molecules of an ideal gas?

At temperature $T \ K$,the $rms$ speed of $CO_2$ is $x \ cm/s$. At what temperature (in $K$) will the $rms$ speed of nitrous oxide $(N_2O)$ be $4x \ cm/s$ (in $T$)?

The ratio of average velocity to most probable velocity is

$\alpha, v$ and $u$ represent the most probable velocity, average velocity, and root mean square velocity, respectively, of a gas at a particular temperature. The correct order among the following is:

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 $.7$)
