Answer the following questions with regard to an alloy of copper with 64 percent of lead that is slowly cooled in a crucible without being stirred from 1100°C to room temperature.
(a) What is the nature of the alloy at 1100°C? (b) Now consider the alloy at a temperature just above the monotectic temperature at 955°C, where it is composed of the two liquids of differenct compositions. Do the liquids have the same density? If not, what would you expect to happen? (c) One of the liquids has the composition of monotectic point. What should happen to this liquid as it passes though the monotectic temperature of 955°C? Describe the physical nature of the contents of the crucible after the alloy is cooled below 955°C, and until it reaches the eutectic temperature at 326°C.
