Using the equilibrium phase diagram shown in Figure, answer the following questions for an alloy $60$ wt$.$ $$Pb-40$ wt: $\%sn$:$(2+3+10+10)$

Determine the temperature at which a starts to form from the liquid. At what temperature does the alloy become completely solid?

Draw and label the cooling curve of the alloy.
