Kinetic Molecular Theory Of Gas. In the case of solids and liquids their physical nature can be described by their shape, size, mass, and volume but in the case of. The kinetic theory of gases is a theoretical model that describes the molecular composition of a gas in terms of a large number of submicroscopic particles like atoms and molecules.

Kinetic molecular theory can be used to explain both charles’ and boyle’s laws. The kinetic theory of gases is a scientific model that explains the physical behavior of a gas as the motion of the molecular particles that compose the gas. To better understand the molecular origins of the ideal gas law, (1) p v = n r t.
