The average velocity of gas molecules is $400 \mathrm{m} {\sec }^{-1}$. Calculate its r.m.s. velocity at the same temperature.

According to kinetic theory of gases

What volume of hydrogen gas, at $273 \mathrm{K}$ and $1 \mathrm{atm}$ pressure will be consumed in obtaining $32.4 \mathrm{g}$ of elemental boron (atomic mass $=10.8$) from the reduction of boron trichloride by hydrogen?

As the temperature is raised from $20°\mathrm{C}$ to $40°\mathrm{C}$, the average kinetic energy of neon atoms changes by a factor :

Which one of the following statements is not true about the effect of an increase in the temperature on the distribution of the molecular speeds in a gas?                             

A gas described by Van der waals equation

The compressibility factor for a real gas  at high pressure is:

If $\mathrm{Z}$ is a compressibility factor, van der Waals equation at low pressure can be written as
