A phase diagram is a map of the equilibrium states for the phase forms and their
combinations that may exist in any system. A point in this space, which represents a
state of the system that is of interest in a particular application, lies within a specific
domain on the map. Reading the map then tells you that, at that state when it comes
to equilibrium:
1. What phases are present.
