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 380j of energy to the room?

A refrigerator considered as a heat pump, releases 380 J of energy into the room. 380 J of energy was removed from the food.

Explanation:

The first law of thermodynamics is related to the law of conservation energy which states that energy can be  transferred from one form to another but can be neither created nor destroyed.

If 380 J of energy was released into the room by refrigerator, then 380 J of energy was removed from the food inside the refrigerator.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
