NEET 2023 Physics Carnot Engine MCQ Question
Type: MCQ-numerical-Medium-Class 11
A Carnot engine has an efficiency of 50% when its source is at a temperature 327° C. The temperature of the sink is :
A
15° C
B
100° C
C
200° C
D
27° C
Correct Answer
Option C
Detailed Explanation
Efficiency η = 1 - T_cold/T_hot. Given η = 0.5 and T_hot = 327 + 273 = 600 K, T_cold = 0.5 * 600 = 300 K, which is 27° C.
