उत्तर
Thermal equilibrium: When a hot cup of coffee is kept in the room, heat flows from coffee to the surrounding air. After some time the coffee reaches the same temperature as the surrounding air and there will be no heat flow from coffee to air or air to coffee. It implies that the coffee and surrounding air are in thermal equilibrium with each other.
Two systems are said to be in thermal equilibrium with each other if they are at the same temperature, which will not change with time.
