In the Carnot engine when the heat is taken from the source, then the temperature of the source
- A remains constant
- B does not remain constant
- C decreases
- D increases
Answer & Solution
Correct Answer
(A) remains constant
Step-by-step Solution
Detailed explanation
Both source and sink in a Carnot cycle have infinite capacity. So, extracting or expelling heat in them does not change their temperatures.
