NEET Physics Entropy MCQ Question
The entropy change can be calculated by using the expression ΔS = qₑₓₜ/T. When water freezes in a glass beaker, choose the correct statement amongst the following.
ΔS (system) decreases but ΔS (surroundings) remains the same
ΔS (system) increases but ΔS (surroundings) decreases
ΔS (system) decreases but ΔS (surroundings) increases
ΔS (system) decreases but ΔS (surroundings) also decreases
Correct Answer
Detailed Explanation
When water freezes, the system becomes more ordered, decreasing its entropy, but the surroundings gain heat, increasing their entropy.
