At what temperature in $^oC$ will the $rms$ speed of $CO_2$ be equal to the $rms$ speed of $CO$ at $STP$?

For a gaseous state,if the most probable speed is denoted by $C^*$,average speed by $\overline{C}$,and root mean square speed by $C$,then for a large number of molecules,the ratio of these speeds is:

Which of the following gases will have the lowest root mean square speed at $25\,^{\circ}C$?

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

Explain the Maxwell-Boltzmann distribution law with a graph.

The distribution of molecular velocities of three gases of molar masses $M_1$,$M_2$,and $M_3$ at $T(K)$ are shown below. The correct relation of their molar masses is:
