1. The problem statement, all variables and given/known data 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. http://edugen.wiley.com/edugen/courses/crs1445/art/qb/qu2/c12/r3-1.jpg What is the latent heat of fusion of this material? What is the latent heat of vaporization of this material? 2. Relevant equations I know that Q = mL equation applies to this concept, but not sure how to go about it 3. The attempt at a solution Q = 100kcal? m = 1 L=Q/m = 100/1 = 100 for fusion?
