Purpose: The purpose of this experiment is to determine the come alive of coalescence of the ice used in this experiment as it undergoes a phase change from solid to liquid (ice to piss) by taking a measured push-down store 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.
