Question

Refrigerator transfers heat from the cold cooling coils to warm surroundings. Which law of thermodynamics favours this process?

• A. Zeroth law of thermodynamics
• B. First law of thermodynamics
• C. Third law of thermodynamics
• D. Second law of thermodynamics

Answer 1

The correct option is D

Second law of thermodynamics

In a refrigerator, 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 favoured.
