<P> Two physical systems are in thermal equilibrium if there are no net flow of thermal energy between them when they are connected by a path permeable to heat . Thermal equilibrium obeys the zeroth law of thermodynamics . A system is said to be in thermal equilibrium with itself if the temperature within the system is spatially and temporally uniform . </P>
