Question

A refrigerator removes 37.0 kcal of heat from the freezer and releases 82.5 kcal through the condenser on the back. How much work was done by the compressor?

Answer 1

work = (37.0 kcal) - (82.5 kcal) = -45.5 kcal

Step-by-step explanation:

The first law of thermodynamics states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. In this case, the refrigerator is removing heat from the freezer and releasing it through the condenser on the back. Therefore, the work done by the compressor is:

work = heat removed - heat released

The negative sign indicates that work was done on the refrigerator by an external agent (e.g., an electric motor) to remove heat from the freezer and release it through the condenser.
