An experiment is performed on an unknown material and produces the following heat curve. The temperature of the material is shown as a function of heat added. If the sample of material has a mass of m = 9.80 g, calculate the specific heat when this material is a solid, cs, and when it is liquid, cl. (Please see the hint panel for the explicit temperatures of fusion and vaporization, do not try to approximate from the graph.)
Hint: This material is found to have a temperature of fusion of Tfusion = 241°C and a temperature of vaporization of Tvapor = 479°C. Use this information along with the points of interest given on the graph and the heat equation to find the specific heat of this material.
