Question

17. A reversible heat engine can be 100% efficient if the temperature of the sink is
(A) Less than that of source
(B) Equal to that of source
(C) 0 degree Celsius
(D) 0 degree Kelvin​

Answer 1

Answer:

option B

Explanation:

equal to that of source

Answer 2

A reversible heat engine can be 100% efficient if the temperature of the sink is Option (b) Equal to that of source.

Explanation:

• Reverse Heat Engine. The reverse heat engine is a device that transfers energy from an object at a lower temperature to an object at a higher temperature by doing work on the system.
• The reversed heat engine transfers the heat from sink to the source with the help of external work.
