NEET Chemistry Entropy MCQ Question
Which of the following combinations correctly describe the behavior of entropy in a system?
Entropy increases when a gas expands and decreases when a liquid crystallizes into a solid.
Entropy is highest in a crystalline solid state compared to a gaseous state.
An increase in temperature always leads to a decrease in entropy.
Entropy changes can only be observed in irreversible processes, not in reversible ones.
Correct Answer
Detailed Explanation
Entropy increases when a gas expands due to greater disorder, and it decreases when a liquid crystallizes into a solid, indicating a more ordered state as stated in the NCERT context.
