Solution:

To melt 1 g of ice into water at 0 C, it needs 336 J of heat energy from the drink. As a result, the bottle loses 336 J more heat energy to 1 g ice at 00 C than it does to 1 g ice-cold water at 00 C. Soft drink bottles are cooled more quickly by ice cubes than by iced water because of this.
