Answer to Question #59198 in General Chemistry for Zain Hassan

Question

The amount of energy gained by the ice cube would be the same as the amount of energy lost by the hot water. Briefly explain why this is true ?

Answer 1

The process of heat exchange is governed by the law of conservation of energy: the energy of an isolated system remains constant.
That is why if we consider the ice cube – water system as an isolated system the provided statement will be right.
However, if the system is not isolated some amount of transferred energy will be lost due to its dissipation.
