Yuliana Benson · Answer 1

477 joules of heat was taken away from the food kept in the refrigerator.

Explanation:

According to the law of thermodynamics which is inferred from the law of energy conservation, energy can neither be created nor be destroyed but it can be transformed from one to another.

Hence when 477 j of energy was released into the room by refrigerator, it means 477 j of heat was removed from the food kept inside the refrigerator.
