Kinetic energy

Vedclass · Answer

(C) According to the kinetic theory of gases,the pressure $P$ exerted by an ideal gas is given by the relation $P = \frac{2}{3} \frac{K}{V}$,where $K$ is the total kinetic energy of the gas molecules and $V$ is the volume.Since the volume $V$ is constant for a given amount of gas,the pressure $P$ is directly proportional to the total kinetic energy $K$ of the gas molecules.This is because pressure arises from the collisions of gas molecules with the walls of the container,and the force of these collisions depends on the kinetic energy of the molecules.Therefore,the correct option is $C$.
