None of these assumptions are strictly true yet the model based on these assumptions can be applied to all gases. Molecules of gas are well separated from each other. As the Postulate 7 of kinetic molecular theory (KMT) suggests, the kinetic molecular theory is directly proportional to the absolute temperature. They continue in a straight line until they collide with each other or the walls of their container. Providence, Rl 02918. In this model, the submicroscopic particles (atoms or molecules) that make up the gas are continually moving around in random motion, constantly colliding not only with each other but also with the sides of any container that the gas is Where c = mean square speed of a gas molecule.

A collection of gas particles in the average kinetic energy is only at a constant ratio to the absolute temperature. We will show that the Kinetic theory of gases developed with these assumptions explain the macroscopic properties of the materials. The average kinetic energy of a gas particle is directly proportional to the temperature. Kinetic theories are available for gas, solid as well as liquid. The molecules of a gas is same and the molecules of different gases are different. The Link Between P and n.
