Question

The refrigerator transfers heat from the cold cooling coils to warm surroundings. Which law of thermodynamics favors this process?

Answer 1

Refrigerator:

1. It is a machine that keeps things cool.
2. It is known by many names like fridge and icebox.
3. It keeps things maintained for household usage at $4-5$ degree Celsius.
4. It takes heat from inside the refrigerator and transfers it out of the refrigerator.
5. It is a heat pump.

The diagram to represent the refrigerator:

Therefore, external work is done by the compressor for the transfer of heat from the cold cooling coils to warm surroundings.

Hence, the second law of thermodynamics is not violated and this process is favored.
