28 g of ice at -100C is dropped in an insulated 75-g aluminum calorimeter cup containing 140 g of water at 300C. (a) Calculate the equilibrium temperature of the container. Specific heats of liquid water, ice and aluminum are 4186 J/(kg 0C), 2090 J/(kg 0C) and 910 J/(kg 0C)respectively. Latent heat of fusion for ice is 3.33 x 105 J/kg. (b) What if, find the final temperature if 68 g of ice had been dropped.
