Refrigeration cycle_________________?
Correct answer: B. Involves transfer of heat from low temperature to high temperature
- A. Violates second law of thermodynamics
- B. Involves transfer of heat from low temperature to high temperature
- C. Both A. and B
- D. Neither A. nor B
Explanation
A refrigeration cycle uses work input to transfer heat from a low-temperature region to a high-temperature surroundings. This does not violate the second law because the required external work is supplied.
