Definitions for "Kinetic theory"
see kinetic molecular theory
(physics) a theory that gases consist of small particles in random motion
A basic set of assumptions for gases and gas behavior. The five assumptions are: Gases are made of molecules in constant, random movement. Gases like Argon have 1-atom molecules. The large portion of the volume of a gas is empty space. The volume of all gas molecules, in comparison, is negligible. The molecules show no forces of attraction or repulsion. No energy is lost in collision of molecules; the impacts are completely elastic. The temperature of a gas is the average kinetic energy of all of the molecules.
