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.
