A theory of the thermodynamic behavior of matter, especially the relationships among pressure, volume, and temperature in gases, based on the dependence of temperature on the kinetic energy of the rapidly moving particles of a substance. The theory uses statistical mechanics under the presumption that energy and momentum are conserved in all collisions between particles.
(General Physics) the kinetic theory a theory of gases postulating that they consist of particles of negligible size moving at random and undergoing elastic collisions. In full: the kinetic theory of gases
