Question

cooling coil in refrigerators are made of _________ to conduct away the heat ​

Answer 1

Answer:

Pressurized by the compressor, the refrigerant vapor enters the condenser coil located outside the refrigerator compartment and rapidly condenses back into a liquid. Another principle of physics manifests: Condensation releases heat. The load of heat energy absorbed inside the refrigerator is now released into the outside air as the liquid refrigerant circulates through the condenser coil. The refrigerant is then conveyed back to the expansion valve, converted again to a vapor, and the evaporation/condensation loop repeats.
