AIPMT PRELIMS 2000 Physics Carnot Engine MCQ Question
Type: MCQ-numerical-Hard-Class 11
The ratio (W/Q) for a carnot – engine is 1 / 6 , Now the temp. of sink is reduced by 62°C, then this ratio becomes twice, therefore the initial temp. of the sink and source are respectively :
A
33°C, 67°C
B
37°C, 99°C
C
67°C, 33°C
D
97 K, 37 K
Correct Answer
Option B
Detailed Explanation
The efficiency of a Carnot engine is determined by the temperatures of the source and sink. Reducing the sink temperature increases efficiency.
