Expert Answer:

ice is more effective than water in cooling liquids because ice needs additional energy to convert itself to water at 0ºC. Thus, it absorbs more heat from the liquid system it is in, making the liquid system cooler. In other words, ice at 0ºC is simply a "level" higher than water at 0ºC. The additional energy requirement is called "enthalpy of fusion.
