Purpose: The purpose of this experiment is to determine the fondness of partnership of the ice used in this experiment as it undergoes a phase change from solid to liquid (ice to piss) by victorious a measured muddle of ice and melting it in water contained in a calorimetric apparatus. Method: In order to determine an accurate measurement of masses and at last heat produced as well as heat of fusion, ane must measure the masses of the apparatus and the mass of the water and ice ( seeively) used in this experiment.
