Specific Heat Labhttp://honolulu.hawaii.edu/distance/sci122/Programs/p21/image.gifAim:Specific heat is the amount of heat per mass required to raise the temperature of 1ÃÂºC. Different materials have different specific heats. The aim of our lab was to determine the specific heat of copper and to compare with the actual result by finding the experimental error.

Materials and equipment:Electrical balanceWaterCalorimeterCylinder of copperThermometerBeakerHotplateCrucible tongsGraduated cylinderGogglesObservations:We started off the lab by filling our calorimeter with 100 cmÃÂ³ of water from the tap. We recorded the initial temperature into our chart and continued to work. We took the cylindrical copper and put it into the beaker filled with water. Our goal was to rise the temperature of the water to 100ÃÂºC. After hitting the goal we pulled out the metal and carefully dropped it into the calorimeter. We watched the temperature going from 26/24 up to 28/27. After collecting all the needed information we plugged in our results into the specific heat formula:Then we made the specific heat of copper ÃÂ X and solved the equation.
