NEET Chemistry First Law MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Based on the first law of thermodynamics, which one of the following is correct?
A
For an isothermal process, q = +w
B
For an isochoric process, ΔU = q
C
For an adiabatic process, ΔU = −w
D
For a cyclic process, q = −w
Correct Answer
Option B
Detailed Explanation
In an isochoric process, volume remains constant, so work done is zero, making ΔU = q.
