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- 9.20 g, calculate the specific heat when this material is a solid, Cs, and when it is liquid, q. (Please see the hint panel for the explicit temperatures of fusion and vaporization, do not try to approximate from the graph.) Temperature (Celsius) 550...
