Q9Multiple choice
The entropy change can be calculated by using the expression ∆S = . 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.
Show answer
(iii) ∆S (system) decreases but ∆S (surroundings) increases.
