An ideal gas at pressure 'P' and temperature 'T' is enclosed in a vessel of volume 'V'. Some gas leaks through a hole from the vessel and the pressure of the enclosed gas falls to $P^1$. Assuming that the temperature of the gas remains constant during the leakage, the number of moles of the gas that have leaked is

$\dfrac{P^1 V}{RT}$

$\dfrac{V}{RT}(P - P^1)$

$\dfrac{2V}{RT}(P + P^1)$

$\dfrac{V}{RT}(P + P^1)$

Assuming the expression for the pressure exerted by the gas, it can be shown that pressure is

$\left(\dfrac{2}{3}\right)^{rd}$ of kinetic energy per unit volume of a gas.

$\left(\dfrac{3}{4}\right)^{th}$ of kinetic energy per unit volume of a gas.

$\left(\dfrac{1}{3}\right)^{rd}$ of kinetic energy per unit volume of a gas.

$\left(\dfrac{3}{2}\right)^{nd}$ times kinetic energy per unit volume of a gas.
