Question

The main feature of carnot refrigeration cycle is that it :

• A. accomplishes the reverse effect of the heat engine.
• B. transfers heat from high temperature to low temperature.
• C. does not need the addition of external work for its functioning.
• D. none of these

Answer 1

Answer: (A)

accomplishes the reverse effect of the heat engine.

Carnot heat engine absorbs heat from a reservoir at higher temperature & delivers heat to a lower temperature reservoir & produces net amount of work.

Carnot refrigeration cycle absorbs heat from a lower temperature reservoir with the help of external work done on the system & delivers the heat to a higher temperature reservoir.

It implies that Carnot refrigeration cycle accomplishes the reverse effect of the heat engine.
