How a refrigerator works - Quiz part 1

What is the primary purpose of a refrigerator?

• To generate cold air

• To remove heat from its interior

• To heat the surrounding environment

• To convert electricity into cold energy

What is the role of the refrigerant in a refrigerator?

• To generate electricity

• To absorb and release heat during phase changes

• To insulate the refrigerator

• To compress air

What happens in the compressor during the refrigeration cycle?

• The refrigerant cools down

• The refrigerant expands and becomes cold

• The refrigerant is pressurized, increasing its temperature

• The refrigerant absorbs heat from the interior

Which component of the refrigerator releases heat to the outside air?

• Evaporator

• Expansion valve

• Compressor

• Condenser

What is the function of the expansion valve in a refrigerator?

• To compress the refrigerant

• To reduce the pressure of the refrigerant, cooling it down

• To heat the refrigerant

• To store the refrigerant

Where does the refrigerant absorb heat inside the refrigerator?

• Compressor

• Condenser

• Evaporator

• Expansion valve

What happens to the refrigerant when it passes through the condenser?

• It absorbs heat from the interior

• It releases heat and condenses into a liquid

• It turns into a gas by absorbing heat

• It is compressed to increase its temperature

Which part of the refrigerator monitors and controls the temperature inside?

• Evaporator

• Compressor

• Thermostat

• Expansion valve

How does the evaporator cool the air inside the refrigerator?

• By releasing heat to the surroundings

• By absorbing heat from the interior with the cold refrigerant

• By increasing the refrigerant’s pressure

• By turning the refrigerant into a liquid

What triggers the compressor to restart the cooling cycle?

• High pressure in the condenser

• Low refrigerant levels

• The thermostat detects the temperature has risen

• The evaporator coils freeze over
