1.) At 200 C, how many different equilibrium phases may exist throughout the entire
composition range in the Cu-Zn system?
2.) What is the difference between pennies minted from 1959 up to 1982, and those after
1982? Be specific.
1. You should already have a Sn-Bi phase diagram with points plotted on it. Attach it to
2. How do your points differ from those on the phase diagram? Why?
3. Briefly explain the thermocouple (Seebeck) effect.

How are they determined?
Lab 2: Phase Diagrams
A system is at equilibrium when it reaches a condition such that the state of the
system no longer changes unless acted upon by some external phenomenon. This
equilibrium condition is seldom reached. What then

Assignment and study guide
Download the Sn-Bi binary phase diagram with grid from WebCT. Set the
phase diagram up for landscape orientation. Using the temperature versus
time curves generated by the class, plot transformation temper
