What Are The Main Postulates Of Kinetic Molecular Theory Of Gases?
This theory led Clausius to derive the kinetic equation and deduced all the gas laws from it. The theory was later on elaborated and extended by Maxwell, who gave the law of distribution of velocities. According to Kinetic Molecular Theory, every gas consists of a large number of very small particles called molecules. The molecules of a gas move haphazardly, cool among themselves and with the walls of the container and change their directions. The pressure exerted by a gas is due to the collisions of its molecules with the walls of a container. The collisions among the molecules are perfectly elastic. The molecules of a gas are widely separated from one another and there are sufficient empty spaces among them. The molecules of a gas have no force of attraction for each other. The actual volume of molecules of a gas is negligible as compared to the volume of the gas. The motion imparted to the molecules by gravity is negligible as compared to the effect of the continued collisions betwe
