The postulates of kinetic molecular theory of gases are
(a) Gases are made up of extremely small particles called molecules.
(b) The gaseous molecules moves randomly in the form of straight line.
(c) The collisions between the gaseous molecules are perfectly elastic.
(d) The pressure of the gas is due to the collision of gaseous molecules on the walls of the container.
( e) There are no intermolecular forces of attraction between the molecules of a gas.
(f) The volume of a gas molecule is negligible compared to the volume occupied by the gas.
(g) The average kinetic energy of gas molecules is directly proportional to the absolute temperature.
