What happens to ice as it warms up

When you add ice to hot water, some of the water’s heat melts the ice. The remaining heat warms the ice-cold water but cools the hot water in the process. You can calculate the mixture’s final temperature if you know how much hot water you started with, along with its temperature and how much ice you added. Two physical properties - - the specific heat and the heat of fusion - - determine exactly how the ice melts and the water cools.
