Which of the following cools the air in a household refrigerator?

Question

Question 13 options:

A)

Reduction of the air temperature because of condensation of the gaseous refrigerant

B)

The transfer of heat to the evaporator because of compression of the liquid refrigerant

C)

Absorption of the heat from the air because of evaporation of the liquid refrigerant

D)

The transfer of heat from the air to the compressor because of expansion of the gaseous refrigerant

Answer 1

The correct answer is:

C) Absorption of the heat from the air because of evaporation of the liquid refrigerant.

In a refrigerator, the cooling effect is achieved through the evaporation process of the refrigerant. The liquid refrigerant absorbs heat from the interior of the refrigerator as it evaporates, which cools the air inside.
