- Kinetic theory
noun 1. 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 kinetic theory A fundamental theory of matter that explains physical properties in terms of the motion of atoms and molecules. In kinetic theory, […]
noun, Physics. 1. a theory that the particles in a gas move freely and rapidly along straight lines but often collide, resulting in variations in their velocity and direction. Pressure is interpreted as arising from the impacts of these particles with the walls of a container.
noun, Physics. 1. a theory that the temperature of a body is determined by the average kinetic energy of its particles and that an inflow of heat increases this energy.
