(b) Figure 3 shows a cool ing curve of Cadmium. Determine Figure 3: Cooling curve for Cadmium. (i) the solidification temperature; (ii) the superheat; (iii) the cooling rate, just before solidification begins; (iv) the total solidification time; (v) the local solidification time; (vi) If the cooling curve was obtained at the center of the casting sketched in the figure, determine the mold constant, assuming that n=2
