Specific Heat Capacity and Heat of Fusion
PHY 200 & 230
The purpose of this experiment is to use the principles of calorimetry to determine the specific heat capacity of an unknown cube sample. To do this, the unknown sample will be heated to a high temperature and then placed into water at a known temperature. By isolating this system, the amount of heat water gains can be determined - which is equal to the amount of heat lost by the object. The students will determine the heat of fusion for ice as well.

Notes
1) The paper clip will be used as a lifting device. There is a bag of lifting devices in D74, where the metal cubes are kept.
2) Do NOT use the Stainless Steel cans!
3) Put the coffee percolator (green) and the blue cooler(s) filled with ice on the counter by the sinks.
4) Put out one of the springy matter models on the instructor's table.
5) Make sure that the room has plenty of paper.
