Experiment No. 302: Heat and CalorimetryRaagas, Michelle Mae G.School of Chemical Engineering, Chemistry, Biological Engineering, and MaterialScience EngineeringMapua Institute of Technology, 658 Muralla St., Intramuros, Manila City, Philippines[email protected]OBJECTIVEEach metal has its own specific heat anddetermining the specific heat of metalsample is the main goal of the experiment.Furthermore, it also aims to determine thelatent heat of fusion of ice. The heat transferfrom its surrounding to a system or bodywill be tackled on this experiment.METHODOLOGY: With the help of laboratory equipment,experiments are made possible. Without thehelp of this devices, the laboratory resultsmay not be as accurate or precise as theyare.Figure 1. Materials used in the experiment(electric stove, calorimeter, thermometers,brass metal, aluminum metal, beaker,weights, digital weighing scale, ice)Jus like the previous experiment, we did thison at the corner of the room to avoid highpercentage error.Calorimetry is the method that is used in thisexperiment. Boiling of water will be donefirst so that it will not be time consumingwhile the other members are weighing themetalandthecalorimeter.Figure 2. Weighing of calorimeterYou will also wish to measure the weight ofwater, to do this, subtract the mass ofcalorimeter with water on it to the mass ofcalorimeter itself. Also, the temperature willbe taken by the use of thermometer. Whenthe water starts to boil, submerge the metalto it and wait again for another time. Then,
