equilibrium between two states
The lines show where a phase changes happens to a substance -
They correspond to only one phase on a phase diagram.
This line is a boundary between two phases.
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.
Phase diagram are also known as thermal equilibrium diagram or a consistutional diagram 1. Different uses of phase diagram are 2. prediction of phase 3. amount of phase 4.composition of phase
(Explanation): If you look at the phase diagram for CO2, and you draw a lines where the temperature and pressure meet, you will see that the point will be inside the zone that is 'solid', so it is in the solid state.
This point is call the "triple point" and this is where all three lines meet together on the phase diagram.
