A metal of atomic weight 27 g/mole, p = 3000 kg/m³, 12 = 4x105 J/kg at Tm = 900 K, l23 || 1.2x10' J/kg at Tev = 1300 K. If cp = 750 + 0.5T, for the solid state and cp = 1200 for the liquid state. a. Draw a heating curve (Temp. vs. time) for a one-kg heated at a rate of 100 W from 300 K to 1200 K b. Find the total amount of heat needed to conduct the process in (a) Find the heat of sublimation (l13) d. Find the change in internal energy Au during melting c.
