Coffee Cup Calorimetry Activities

A coffee cup calorimeter is a relatively low tech device that can yield some remarkably good results when used well. It typically consists of
  • two coffee cups nested together (in order to provide isolation from the surroudings)
  • a lid with holes for a thermometer and stirrer
  • a thermometer to measure temperature changes
  • a stirrer to aid in maintaining uniform temperature

Each coffee cup calorimeter differs from all others in its ability to absorb or release heat. The measure of a coffee cup calorimeter's heat absorbing properties is called its heat capacity. The heat capacity of each calorimeter is determined experimentally. Before doing experiments, you will need to calibrate your calorimeter. If you have already performed a calibration on your calorimeter and know its heat capacity, you can proceed directly to the experiments page. However, if you need to learn more about this process and to perform the calibration, follow the "calibrate" link below.

General Directions . . . (a) get a worksheet, (b) calibrate your calorimeter, and (c) perform some experiments.
Be sure to take good notes . . . you will need to use information from some page on others!
