Answer the following questions by using the phase diagram in Exercise 11.43.

(a) Sketch the heating curve that is expected when heat is added to the sample at constant pressure, starting at point B.

(b) Describe what happens if the pressure is lowered at constant temperature, starting at point A.

(c) What does the positive slope of the solid-liquid equilibrium line tell you about this substance?
