NEET Physics Laws of Thermodynamics MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a diagram showing an isothermal expansion of an ideal gas into a vacuum. What is the change in internal energy (∆U) in this process?
A
∆U = 0
B
∆U is positive
C
∆U is negative
D
∆U depends on the volume change
Correct Answer
Option A
Detailed Explanation
In an isothermal expansion of an ideal gas into a vacuum, the change in internal energy (∆U) is zero since the temperature is constant and no work is done.
