NEET Chemistry Entropy MCQ Question

Type: MCQ-conceptual-Medium-Class 11

The entropy change can be calculated by using the expression, ΔS = qrev/T. When water freezes in a glass beaker, choose the correct statement amongst the following:

A

ΔSsystem decreases but ΔSsurroundings remains the same.

B

ΔSsystem increases but ΔSsurroundings decreases.

C

ΔSsystem decreases but ΔSsurroundings increases.

D

ΔSsystem decreases and ΔSsurroundings also decreases.

Correct Answer

Option C

Detailed Explanation

When water freezes, the system loses entropy (ΔSsystem decreases), but the surroundings gain entropy due to the release of heat, leading to an increase in ΔSsurroundings.
