When ice cubes are made, the entropy of water
-
- does not change
- decreases
- increases
- may either increase or decrease depending on the process used
- does not change
Correct Option: B
When water is frozen into ice, the temperature drops below 0°C. Since the entropy of the solid is less than that of the liquid, the entropy of the water (the system here) will decrease on freezing. The amount of decrease is found by dividing the heat of fusion of ice by the temperature for the reversible pathway.
