Abstract
Thermal and caloric equations of state for a dilute gas under a heat f lux are used to provide a possible microscopic interpretation of tempe rature in nonequilibrium states. Two possible experiments in which thi s nonequilibrium temperature could be shown are discussed. They includ e the study of the Doppler broadening of spectral lines, and of the ve locity of long sound waves, both ina nonequilibrium situation characte rized by a steady heat flux.
