If a gas expands at constant temperature,it indicates that

The kinetic energy of $2 \, \text{moles}$ of $N_2$ gas at $27 \, ^oC$ is .............. $J$.

Given that the atomic weights of carbon,nitrogen,and oxygen are $12$,$14$,and $16$ respectively,which of the following pairs of gases will diffuse at the same rate?

According to the Kinetic Molecular Theory of Gases,which of the following statements is correct?

According to the kinetic molecular theory of gases, which of the following statements are correct?
$a$) The actual volume of the molecules is negligible in comparison to the empty space between them.
$b$) Collisions of gas molecules are inelastic.
$c$) At any particular time, different particles in the gas have the same speed and same kinetic energies.
$d$) Pressure is exerted by the gas as a result of the collision of the particles with the walls of the container.

Internal energy and pressure of a gas per unit volume are related as
