Web5. Phase Diagram for a Pure Substance: Pure substance is a substance consisting only of a single molecular species such as He, H 2, H 2 O or NH 3, phases of these substances being different namely solid, liquid and gaseous. Figure 10.3 shows such a diagram where the phase changes are shown. Such a diagram is called a phase diagram for pure ... WebThe shape of a phase diagram is almost the same for each pure substance. Several phases can coexist if the pressure and temperature conditions are on the phase separation curve. The most common example is an ice cube in a glass, if the temperature between the liquid and the solid is precisely 0°C and the air is also at 0°C, then their state ...
