Which of the following cools the air in a household refrigerator?
a. reduction of the air temperature due to condensation of the gaseous refrigerant
b. absorption of the heat from the air due to evaporation of the liquid refrigerant
c. the transfer of heat from the air to the compressor due to expansion of the gaseous refrigerant
d. the transfer of heat to the evaporator due to compression of the liquid refrigerant

All of the above according to one source hence,
A. Reduction of the air temperature due to condensation of the gaseous refrigerant
B. Absorption of the heat from the air due to evaporation of the liquid refrigerant
C. The transfer of heat from the air to the compressor due to expansion of the gaseous refrigerant
D. The transfer of heat to the evaporator due to compression of the liquid refrigerant

A refrigerator enables the air inside its space cool down and prevents heat from getting inside as to maintain the cool air as much as possible.
Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.

Power allows people to take initiative and dish out duties for others to do and accomplish. it also can be used to create policies and rules people need to abide by. it basically just creates order.
