Looking at the water phase diagram above, it’s probably common since most people are familiar with three phases of water — solid (ice), liquid (water), and gas (vapour) — and with the fact that an increase in temperature will cause water to change from one state to another. The gas and liquid phases are quite straightforward. Notice one key difference between the general phase diagram and the phase diagram for water. In water’s diagram, the slope of the line between the solid and liquid states is negative rather than positive. The reason is that water is an unusual substance in that its solid state is less dense than the liquid state. Take a look at the following phase diagrams of water below.
The critical temperature (T c ) of a substance is the highest temperature at which the substance can possibly exist as a liquid. The critical pressure (P c ) is the pressure that must be applied to the gas at the critical temperature in order to turn it into a liquid. The critical point is the intersection point of the critical temperature and the critical pressure.
