  1. You have a beaker containing 100 mL of water. The initial temperature of the water is 200C. (Note: One mL = 1 cm3).
  1. You place a piece of copper into the beaker containing. When you do, the water level increases to 110.5 mL. What is the mass of the copper in grams?
  2. If the temperature of the water increases to 350C, how much heat (in calories) did the copper add to the water?
  3. You now add a piece of iron to the same beaker with the copper and the water level increases from 110.5 mL to 113 mL. What is the mass of the iron in grams?
  4. Upon being added to the water, the temperature of the iron drops by 300C. How much heat in total (iron and copper) was added to the water?
