The main feature of Carnot refrigeration cycle is that, it________________________?
Correct answer: C. Accomplishes the reverse effect of the heat engine
- A. Does not need the addition of external work for its functioning
- B. Transfers heat from high temperature to low temperature
- C. Accomplishes the reverse effect of the heat engine
- D. None of these
Explanation
A refrigerator operates as the reverse of a heat engine: it uses work to transfer heat from a low-temperature region to a high-temperature region. The Carnot refrigeration cycle is the ideal reversible version of this reverse effect.
