20.) You want to raise the temperature of ice at 0 degrees Celsius to steam at 110 degrees O Celsius. The specific heat of water is 4.184 J/Cg. The specific heat of steam is 2.01 J/Cg, and the specific heat of ice is 2.03 J/Cg. Ice has a heat of fusion at 334 J/g and water has a heat of vaporization of 2260 J/g. Find the Q for this raise in temperature.
1. Suppose the sun were used as a heat source to warm some water in a solar-heated house or swimming pool.

How many kcal are needed to convert 20 g of ice at 0EC to steam at 100EC? 3. What would be the final temperature of the water resulting from the addition of 20 g of steam at 100EC to 80 g of ice at 0EC?
