Question

If a refrigerator is heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 333j of energy to the room?______Joules

Answer 1

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but cannot be created or destroyed. so assuming no heat losses then heat removed is also 333 J
