A graph of three variables (such as P, V, & T) requires three dimensions and is often asurface rather than a line as for the 2-D graphs. A 3-D Phase diagram (with only one component): A surface representing the properties of a typical pure substance (what a theoretical equation of state would have to account for) Each point on the curving surface represents a set of values of the pressure, temperature, and molar volume that can be attained by this substance. 26.
