If a refrigerator is a heat pump that follows the first law of thermodynamics how much heat was removed from food inside of the refrigerator if it released 240J of energy to the room?

1 Answer

Answer :

Not enough information. The refrigerator must also follow theSecond Law.The energy released to the room is the energy removedfrom the room, PLUS the energy used by the refrigerator (forexample, as electrical energy).
