Question \( 3(10 / 100) \) A T-P phase diagram for a unary system (pure A) is given here, and it shows four phases. Construct a reasonable T vs. \( \mu \) (Temperature Chemical potential) property diagram at \( \mathrm{P}_{1} \). It should show all the stable and metastable two-phase equilibria at \( \mathrm{P}_{1} \). Hint: The T values for all the two-phase equilibria at \( P_{\text {, are easily }} \) found by extrapolation. Approximate all the \( T-\mu_{A} \) lines by straight lines, intersecting at the two-phase equilibria.
