A frictional metal of atomic weight 27 has a density of 3000kg m-3. The heat of fusion is 4*10^5J kg^-1 at the melting point (900k), and at the boiling point (1300k) the heat of vaporization is 1.20*10^7J kg^-1. For the solid, cp can be given by 750+0.5T in J kg^-1 and in the liquid cp is 1200J kg^-1 k^-1 independent of temperature.
(a) Draw a curve of temperature versus time as 10 g of this metal are heated at a constant rate of 1W from 300 to 1200k.
(b) Determine the amount of heat necessary to cause this temperature change.
