... a theory based on a simplified molecular or particle description of a gas, from which many gross properties of the gas can be derived.

The British scientist James Clerk Maxwell and the Austrian physicist Ludwig Boltzmann, in the 19th century, led in establishing the theory, which became one of the most important concepts in modern science.
