A household refrigerator keeps food cold primarily by using a refrigerant that repeatedly does what?

AAbsorbs heat as it evaporates inside the refrigerator, then releases that heat outside as it condenses
BGenerates electricity directly
CFreezes permanently and stays solid
DBurns to generate heat

Explanation

A household refrigerator works by circulating a special fluid called a refrigerant through a closed loop of tubing, where it absorbs heat from inside the refrigerator as it evaporates into a gas, and then releases that absorbed heat to the surrounding room as it’s compressed and condenses back into a liquid outside the main compartment. This continuous cycle of evaporation and condensation effectively transfers heat from inside the refrigerator to the outside air, keeping the interior consistently cool. Modern refrigerants have been reformulated over time partly due to environmental concerns associated with some older refrigerant chemicals.
