NEET Physics First Law of Thermodynamics MCQ Question
Type: MCQ-numerical-Medium-Class 11
A diatomic gas (γ = 1.4) does 100 J of work when it is expanded isobarically. The heat given to the gas is:
A
250 J
B
200 J
C
350 J
D
450 J
Correct Answer
Option A
Detailed Explanation
For an isobaric process, the heat given is related to the work done and the change in internal energy. Using the formula Q = W + ΔU and the specific heat ratio, the heat given is 250 J.
