Question

The soft drink bottles are cooled by

1. ice cubes at 0°C
2. iced-water at 0°C.

Which will cool the drink quickly? Give reason.

Answer 1

Cooling ice-cube at 0°C The energy required to melt 1 gram of ice cubes at 0°C is 336 joules, meaning that soft drinks dissolve into water more rapidly. So, at 0°C, 1 gram of ice loses 336 J more heat energy than 1 gram of iced water does in drinks.
