Question

In a Carnot’s engine, as the gas gives heat energy to the sink, then the temperature of the sink

• A. increases
• B. decreases
• C. remains constant
• D. becomes zero

Hint:

In Carnot engines, the temperature of the cold sink remains constant while heat is transferred from the gas.

Answer 1

The Correct Option is C

In a Carnot cycle, the engine operates between a hot reservoir and a cold sink. When the gas gives heat energy to the sink, it does not alter the temperature of the sink because the sink is typically assumed to be at a constant temperature. Thus, the temperature of the sink remains constant. Therefore, the correct answer is: \[ \boxed{\text{remains constant}} \]
