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 :
(i) ΔS (system) decreases but ΔS (surroundings) remains the same.
(ii) ΔS (system) increases but ΔS (surroundings) decreases.
(iii) ΔS (system) decreases but ΔS (surroundings) increases.
(iv) ΔS (system) decreases and ΔS (surroundings) also decreases.
