NEET Physics Entropy MCQ Question
Type: MCQ-conceptual-Easy-Class 11
Which of the following statements about entropy and internal energy is correct?
A
The change in internal energy is independent of the process type, while entropy can vary between reversible and irreversible processes.
B
Entropy is always constant for all processes regardless of reversibility.
C
Internal energy increases with an increase in entropy for all systems.
D
Entropy decreases when a gas expands irreversibly.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the change in internal energy (∆U) does not discriminate between reversible and irreversible processes, while the change in entropy (∆S) does. This highlights the difference in behavior between these two thermodynamic quantities.
