Question

What is thermal equalibrium

Answer 1

Thermal equilibrium between two systems means there is no heat flow from one system to another.  This means that the two systems are at the same temperature.

Total heat content remains same in a system.

Answer 2

Answer:

Two physical systems are in 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.
