On colliding in a closed container,the gas molecules:

If the momentum transferred by gas molecules to the walls of a container is $p_1 = nmAv_x^2 \Delta t$,then derive the equation for the pressure of the gas.

Define temperature in view of kinetic energy of a gas.

The temperature of a gas is $-78^{\circ} C$ and the average translational kinetic energy of its molecules is $K$. The temperature at which the average translational kinetic energy of the molecules of the same gas becomes $2K$ is: (in $^{\circ} C$)

The average kinetic energy of thermal neutrons is of the order of (Boltzmann's constant $K_B = 8 \times 10^{-5} \text{ eV/K}$ and room temperature $T \approx 300 \text{ K}$)

Consider a gas with $n$ molecules. The average number of molecules moving in a fixed direction is ..........
