  • Abstract : We present a linear state equation between kinetic temperature and mass density that has been widely verified in boundary-driven one-dimensional nonequilibrium systems. We show that this relation holds even more universally and in particular when standard relations between purely mechanical and thermodynamic quantities do not apply. We investigate special situations in which phase transitions occur and the relation fails, as common in statistical mechanics. We also provide a theoretical explanation of how this happens.
