The general form of a phase diagram is given below. Observe that this phase diagram is divided into three regions by the blue boundary lines similar to the way the interactive phase diagram for CO_2 was divided. Compare this general form of this phase diagram with the interactive phase diagram for CO_2 and classify points a through g on the phase diagram according to the number of phases present at each point.
