Enthalpy of neutralization introduction energy changes always accompany chemical reactions if energy, in the form of heat, is liberated the reaction is exothermic and if energy is absorbed the reaction is endothermic. Conclusion 3 it is assumed that the glass stirrer, the digital thermometer and the calorimeter were not absorbing any heat but in reality these instruments are. Calorimeter is used because the knowledge f the amount of energy needed to produce a reaction is extremely useful to scientists studying chemistry coffee-cup calorimeter occurs inside of a styrofoam cup.
