ABSTRACT
Calorimetry studies the amount of heat that flows through a physical or chemical change into its surroundings. What occurs in an ammonium nitrate cold pack illustrates two examples of where a study in the area of calorimetry is relevant. In the first example, a calorimeter is used to measure the heat flow for the process of the solvation reaction of ammonium nitrate and water. The second example involves the specific heat of water.
