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
