JCE Classroom Activity
Some Like It Hot, Some Like It Cold
Robert G. Silberman
Sciencenter, Ithaca, NY 14850
Cover
January 2004
Vol. 81 No. 1
p. 64A
Abstract
Students combine liquids and solids in a calorimeter and use a thermometer to determine if the reaction mixture gets hotter or colder. The goal is to find a combination of a liquid and a solid that could serve as the basis for a cold pack of the type used for athletic injuries. The Activity is done on a small scale but can be modified for a larger scale.
