Discussion: In this experiment, the goal was to observe the heat changes of four different reactions so we could determine the heat capacity and enthalpy. A calorimeter, which measures the heat flow in the reaction and ideally loses no energy to the surroundings, was used to help observe these changes. In part one of the experiment, the goal was to determine the heat capacity of the calorimeter (Ccal). This is the amount of energy required to raise the temperature of a substance by one degree under constant pressure. The total heat of the reaction is equal to the heat absorbed by the calorimeter and the solution. The heat absorbed by the calorimeter (q) is equal to its heat capacity (Ccal) times the change in temperature. The Ccal is important because it will be used to calculation the heat of reaction in the other parts of the experiment. It is important to obtain the value of Ccal twice to ensure that a consistent value is determined since the value of Ccal will be used throughout the rest of
