Question

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 222J of energy to the room?

Joules

Answer 1

by following the first law of thermodynamics, i think the refrigerator moved 222 J of energy from the food.
This will make the food colder but at the same time releasing the exact amount to the environment around it.
