Question

Quizplus · Accepted Answer

A refrigerator works by removing heat from its contents and expelling it to the outside environment. Therefore, it must give off more heat than it absorbs in order to cool its contents. This concept is expressed by the coefficient of performance (COP), which is the ratio of heat removed from the contents to the work done by the refrigerator's compressor. A COP greater than 1 indicates that more heat is removed than work is done, meaning that the refrigerator is giving off more heat than it absorbs.
