Heat is added to a 1.0-kg solid sample of a material at -200 C. The figure shows the temperature of the material as a function of the heat added. (a) What is the latent heat of fusion of this material? (b) What is the latent heat of vaporization of this material? (c) What is the specific heat capacity of this substance in its solid state? (d) What is the specific heat capacity of this substance in its liquid state? 300 200 - 100- Temperature *C -100 - -200 - 180 360 540 720 900 Heat Added (kcal)
