1) Your styrofoam cup weighs 6 grams. You put some water in it, and the partly filled cup now weighs 91 grams. The water’s temperature is 18°C. A large glass marble that weighs 35 grams is moved from boiling water and added to the water in the cup. Soon the water in the cup is 47°C. What is the relative head capacity of the glass (marble)?

2) IF Heat Capacity is a function of the overall mass of the items moved from the boiling water into the cup, then design a simple experiment to show that this is the case.

3) IF the case in #2 is true, then what would a graph of Rel. Heat Cap. vs Atomic Weight look like? (Either draw such a graph or describe it.)

4) IF Heat Capacity were not a function of mass of the items moved from the boiling water into the cup, then what would a graph of Rel. Heat Cap versus Atomic Weight look like IF higher atomic weights had higher heat capacities? (Either draw such a graph or describe it.)
