A phase diagram is a pressure-temperature graph that shows the ranges of temperature and pressure over which each phase is stable.
The phase diagram is divided into three regions, each region representing one stable phase: solid, liquid, or gas. There are three boundary lines that separate the phases from one another. These boundary lines represent the equilibrium between two phases. The point at which the three boundary lines intersect is called the triple point. All three phases can exist in equilibrium with each other at this point.
Use the phase diagram for CO 2 and determine which of the following statements are correct.
