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 300J of energy to the room?

Answer:____________ unit:_______

Answer 1

300 J.

Step-by-step explanation:

• The first law of thermodynamics is the law that demonstrates the conservation of energy.

• It states that the total energy of an isolated system can not be created or destroyed, but it may be transformed into another form.

• The energy released to the room is 300 J.

• So, according to the law of conversation of energy; the amount of heat removed from food inside of the refrigerator is 300 J.
