Physics - ice to liquid
Fifty grams of hot water at 80oC is poured into a cavity in a very large block of ice at 0oC. The final temperature of the water in the cavity is then 0oC. Show that the mass of ice that melts is 50 g. To melt ice to 50g of water, I think that it will take: 50g(334J/g) = 167,...
