Abstract

On a microscopic level a gas is comprised of material particles at various levels of internal excitations, moving randomly in space (executing thermal or kinetic motions). The problem of the kinetic theory of gases is to determine the distributions of the thermal velocities and of the level populations. This task is complicated by the fact that these distributions are determined by the combined effects of a number of competing mechanisms, including collisions between the particles as well as various radiative processes.
