NEET Physics Heat Engines MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a heat engine operating between two reservoirs. The engine receives 600 J of heat from the hot reservoir and expels 400 J to the cold reservoir. What is the work done by this engine?
A
200 J
B
1000 J
C
400 J
D
0 J
Correct Answer
Option A
Detailed Explanation
The work done by the heat engine is the difference between the heat absorbed from the hot reservoir and the heat expelled to the cold reservoir, which is 600 J - 400 J = 200 J.
