Question:
The entropy change can be calculated by using the expression ∆S = qrev/T
When water freezes in a glass beaker, choose the correct statement amongst
the following :
(i) ∆S (system) decreases but ∆S (surroundings) remains the same.
(ii) ∆S (system) increases but ∆S (surroundings) decreases.
(iii) ∆S (system) decreases but ∆S (surroundings) increases.
(iv) ∆S (system) decreases and ∆S (surroundings) also decreases.
Solution:
Option (iii) is the answer.
