A chemical has the following properties: normal melting point
120 oC, normal boiling point 200 oC, triple point 100 Torr and 50
oC. Sketch the approximate phase diagram and label
the solid, liquid, and gaseous phases and the
solid-liquid, liquid-gas, and solid-gas phase boundaries. (b)
Sketch an approximate heating curve for a sample at constant
pressure, beginning at 400 Torr and 25 oC and ending at 250
oC.
