Question
Why do bottled soft drinks get cooled, more quickly by the ice cubes than by the iced water, both at 0℃?
Solution
This is because 1 g of ice at 0oC takes 336 J of heat energy from the bottle to melt into water at 0oC. Thus, bottle loses an additional 336 J of heat energy for 1 g of ice at 0oC than for 1 g iced water at 0oC. Therefore, bottled soft drinks get cooled, more quickly by the ice cubes than by iced water.
