Say we put a glass of water in a room, and after some time the water temperature will be same as the temperature of the room and equilibrium is achieved between them. The glass of water becomes stable. Now, if we place a glass of hot water near the previous glass then this glass of water becomes hot too, and after some time, equilibrium is achieved between both glasses and the room. But why does the first stable glass of water absorb more heat as it already is in equilibrium?

Suppose we put a glass of water in a room. After some time, the water temperature will be same as the temperature of the room and equilibrium is achieved between them. The glass of water becomes stable. Now, if we place a second glass of hot water near the first glass, then the first glass of water becomes hot too, and after some time, equilibrium is achieved between both glasses and the room. But why does the first stable glass of water absorb heat if it already is in equilibrium?
