... Part III: Calibration of the Calorimeter In order to account for all of the heat produced by a reaction in the calorimeter, it is important to determine how much heat the calorimeter itself absorbs. This can be accomplished by combining two masses of water, one “hot” and one “cold”. If the coffee cu ...
