an experiment is performed on an m=8.00g sample of an unknown material and produces the given heat curve. the temperature of the material is plotted a a function of heat added. in the table, T1= 45.2C, E1= 169 j, E2= 836J, E3=1430J, and E4= 2830J. other experiments determine that the material has a temperature of fusion of Tfusion= 237C and a temperature of vaporization of Tvapor=473C. calcualte the specific heat c of this material when it is a solid. calculate the specific heat c of this material when it is a liquid
