E302: HEAT AND CALORIMETRY MONDEJAR, Calvin Paulo A. OBJECTIVE The purpose of this experiment is to find out the metals’ specific heat and to find out the fusion of ice’s latent heat. The determination of the value of the metals’ specific heat is significant for the metals’ specific heat experimental value will find out its comparison to the metals’ actual value of specific heat by percentage of error formula. The determination of fusion of ice’s latent heat is also significant because the experimental value of fusion of ice’s latent heat will find out its comparison to the latent heat of fusion of ice’s actual value by percentage of error formula. The experiment has been performed in order to gather data that will provide some answers to the problem. The experiment sought for the metals’ specific heat and the latent heat of fusion of ice. The experimental values of the metals’ specific heat and the fusion of ice’s latent heat were found out through the experimental procedures of the experiment conducted. The experiment measured the mass of metal, calorimeter, water, and ice; the initial temperature of metal, calorimeter, water, and ice; the final temperature of the mixture; and the experimental and actual values of the two trials in the experiment. The motivation was to get the best possible percentage of error as well as performing the experiment correctly. MATERIALS AND METHODS Materials for the Heat and Calorimetry experiment were used to collect data required for the metals’ specific heat and the ice’s latent heat of fusion. In part 1 of the experiment, which is the determination of the specific heat of metals, the materials used were: electric stove for heating the water contained in the beaker, a calorimeter for determining heat amount or Calorimetry, a thermometer used to measure temperature of the metals and water, an aluminum metal used as a sample metal for the 1 st trial of part 1, a copper metal used as a sample metal for the 2 nd trial of part 1, a beaker used as a container for the water, a digital weighing scale for determining the mass of the metals, calorimeter and ice. In part 2 of the experiment, which is the latent heat of fusion of ice, the ice was included in the materials needed. FIGURE 1. Materials utilized for the heat and calorimetry experiment. Before the experiment conducted, materials were arranged and prepared, making sure that the electric stove was plugged in the socket, the beaker was filled with water and checking the other materials for the 1 st part of the experiment, which is the determination of the metals’ specific heat and for the 2 nd part of the experiment, which is the fusion of ice’s latent heat. In the 1 st part of the experiment, the determination of the metals’ specific heat was conducted. In the 1 st trial, an aluminum metal, as 1 st trial’s sample metal, was measured by its mass ( m m ) in grams through the utilization of the digital weighing scale. After the determination of aluminum metal’s mass, the mass of the calorimeter ( m c ) in grams and the mass of
