1. Find the quantity of heat required to change 100 g of solid aluminum at 650 C to liquid aluminum at 660 C. The melting point of aluminum is 660.
2. Calculate the amount of heat lost when 35 g of steam at 100 C are changed to ice at - 20 C.
3. When 10g of ice 0 C are placed in glass of water at 24 C the ice melts and the final temperature of the water 20 C. Calculate the mass of the water in the glass.
