The average translational kinetic energy of the oxygen molecules at a temperature of $127^{\circ} C$ is (Boltzmann constant $= 1.38 \times 10^{-23} \,J \,K^{-1}$)

By using which equation can the force acting on the walls of a container due to gas molecules be obtained?

$A$ gas is filled in a container at pressure ${P_0}$. If the mass of all molecules is halved and their $rms$ speed is doubled,what will be the new pressure?

$E_0$ and $E_H$ respectively represent the average kinetic energy of a molecule of oxygen and hydrogen. If the two gases are at the same temperature,which of the following statements is true?

$Assertion$: The total translational kinetic energy of all the molecules of a given mass of an ideal gas is $1.5$ times the product of its pressure and its volume.
$Reason$: The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.

The internal energy of a monoatomic ideal gas molecule is
