The freezing point of water at sea level is 0°C. This temperature can be changed, however, by adding impurities in water. Sprinkling salt on road surfaces on an icy day melts the ice by lowering the melting temperature. Salt is also used in simple ice cream machines during cooling of the cream. In an ice cream machine, the vessel containing the ice cream mixture is cooled by concentrated brine (salt-water solution) which has a temperature that is lower than the freezing point of ice cream mixture. Another consequence of the decrease in freezing point due to impurities is the soft texture of ice cream. As ice cream freezes, the remaining liquid becomes more and more concentrated with sugar and other impurities. The concentrated liquid has a much lower freezing temperature than water. As a result, ice cream never completely freezes, and retains the characteristic soft texture.
