The heat generated by a reaction causes the temperature of a solution to rise. By measuring this temperature change, and relating it to the heat capacity, one can find the amount of heat generated in a reaction. A “calorimeter” is an insulated device in which the reaction is carried out. Experiment 25 Pre-Lab Questions. Experimental Procedure, Part A.
