Explanation:

Answer 2

Heat transmission in the evaporator of a refrigeration system:-

• The evaporator collects heat from the chilled compartment and stores it in a "bucket."
• The "bucket" is low-pressure, and when it absorbs heat, it changes state (latent heat transfer).
• The low-pressure, heat-filled "bucket" is then moved to the compressor by the evaporator.

The transfer of heat in an air conditioner:-

• A cold liquid refrigerant absorbs heat from the hotter portion of the evaporator, cooling it down.
• The refrigerant is then converted to a gas and compressed to raise its temperature.
• The refrigerant then passes over condenser coils, which transfer heat from the refrigerant to the surrounding air.

Heat transfer in the radiator of the car:-

• The usual mechanisms for heat transfer from a radiator are thermal radiation, convection into flowing air or liquid, and conduction into the air or liquid.
• A radiator can even transfer heat by phase change, such as when drying socks.
