equilibrium between two states
This line is a boundary between two phases.
They correspond to only one phase on a phase diagram.
The lines on a phase diagram represent the boundaries between the different phases of a substance (such as solid, liquid, and gas). These lines show the conditions of temperature and pressure at which two phases can exist in equilibrium with each other.
meet at the critical point on the diagram.
The simplest phase diagrams are pressure-temperature diagrams of a single simple substance, such as water. The axes correspond to the pressure and temperature. The phase diagram shows, in pressure-temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas.

A phase diagram of the equilibrium relationship between temperature, pressure, and composition in any system.
To effectively interpret a ternary phase diagram, one must understand the composition of the three components involved, the boundaries between different phases, and how changes in temperature and pressure affect the phases present. By analyzing the intersections of lines and regions on the diagram, one can determine the phase stability and composition of a system at different conditions.
To read a phase change diagram effectively, look at the temperature and pressure axes to determine the state of the substance (solid, liquid, gas). Follow the lines to see how the substance changes phases at different conditions. Pay attention to the slopes of the lines, which indicate the rate of change between phases.
