Question:
Efficiency of a Carnot engine
Efficiency of a Carnot engine
Show Hint
Carnot engine efficiency depends only on reservoir temperatures.
Updated On: Apr 21, 2026
- depends on the nature of the working substance
- does not depend on the nature of the working substance
- depends only on the temperature of the source \( T_1 \)
- depends only on the temperature of the sink \( T_2 \)
- does not depend on both temperature of the source \( T_1 \) and temperature of the sink \( T_2 \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
\[
\eta = 1 - \frac{T_2}{T_1}
\]
Step 1: Observation.
Efficiency depends only on temperatures.
Step 2: Conclusion.
Independent of working substance.
