Thermal equilibrium

Thermal calm is accomplished back two systems in thermal acquaintance with anniversary added cease to accept a net barter of energy. It follows that if two systems are in thermal equilibrium, again their temperatures are the same.

Thermal calm occurs back a system's arresting thermal observables accept accomplished to change with time. For example, an ideal gas whose administration action has stabilised to a specific Maxwell-Boltzmann administration would be in thermal equilibrium. This aftereffect allows a distinct temperature and burden to be attributed to the accomplished system. Thermal calm of a arrangement does not betoken complete accord aural a system; for example, a river arrangement can be in thermal calm back the arresting temperature administration is abiding and not alteration in time, alike admitting the spatial temperature administration reflects thermal abuse inputs
