Abstract
The BGK model for an ideal gas with an internal degree of freedom introduce s two characteristic times into the Boltzmann equation, accounting for the times between elastic and inelastic collisions, respectively. Moment equati ons are derived from the Boltzmann equation and the influence of the charac teristic times is studied for some processes, such as heating, sound waves and shocks.
