Lesson 8 1 Lesson 8 Kinetic theory of gases The kinetic theory of gases is a model for gas behaviour. A model describes a given real system by some of its most important features. The ideal gas law, as used thus far, is an empirical model for gas behaviour. The kinetic theory of gases provides a theoretical justification ( theoretical model ) for the ideal gas law Lesson 8 Hypotheses A gas is composed of a very large number of small particles in constant, random, straight-line motion Gas molecules are separated by a large distance – a gas is mostly empty space Molecules collide with one another and with the walls of the container There are no intermolecular forces, except during collisions – molecules act independently of one another Individual molecules may gain or lose energy during collisions but the energy of the entire gas remains constant – molecular collisions are elastic Lesson 8 Relation between gas pressure and velocity Translational kinetic energy of a molecule:
