Type: MCQ-numerical-Hard-Class 11
The volume (V) of a monatomic gas varies with its temperature (T), as shown in the graph. The ratio of work done by the gas, to the heat absorbed by it, when it undergoes a change from state A to state B, is
A
1/3
B
2/3
C
1
D
2
Correct Answer
Option C
Detailed Explanation
For a monatomic ideal gas, the work done is related to the change in volume and the heat absorbed is related to the change in temperature. The ratio can be derived using the first law of thermodynamics.
