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 258J of energy to the room?
Joules

Answer 1

Oooh okay... so recall that:
First law of thermodynamics:
"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."

In this case -->
the
Energy of the surroundings (fridge) is 258J

Answer 2

@j3nny0rtiz what do you think?

Answer 3

Typoo...
Energy of the universe***(room)= 258J
Recall that the:
system+surroundings=universe**
