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.
