Question

what is thermal equilibrium???

Answer 1

two physical systems are in thermal equilibrium if here is no net flow of thermal energy between thm when they are connected by a path permeable to heat..

Answer 2

thermal equilibrium if there is 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.
