Temperature Experiments

Calorimetry: The MicroLab thermistor (Model 103) in conjunction with a stirrer and Dewar flask (or other insulated container) make a great calorimeter. Precision timed electrical heating and simultaneous temperature measurement to determine the calorimeter heat capacity can be accomplished using the MicroLab Interface (Model FS-524), thermistor, and Control Module, 12 VDC (Model 255) and accessory heater. Voila! Your MicroLab system has just become a very good and inexpensive solution calorimeter.

This is a list of articles on solution calorimetry through about 2008. It is not a complete list, but it does have some interesting lab applications.

Thermochemistry to the Rescue: A Novel Calorimetry Experiment for General Chemistry
Michael W. Vannatta and Michelle Richards-Babb, Robert J. Sweeney
J. Chem. Educ., 2010, 87 (11), pp 1222–1224

Interesting – and also a very good bibliography of solution calorimetry experiments in its references.

The Enthalpy of Decomposition of Hydrogen Peroxide: A General Chemistry Calorimetry Experiment
