Phase Diagrams for Waters

Free and printable examples of phase diagrams for waters are available on this page. These examples will give you a brief overview of the concept of the phase diagram of water. The first one below is the pressure bar diagram for the water phase.

The simplest phase diagrams for water are pressure-temperature diagrams of a single simple substance. Notice several elements present in the diagrams. 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. Solid water (ice) is less dense than liquid water just above the freezing point. More phase diagram for water is shown in the picture below.

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. Ice floats in liquid water. Therefore, a pressure change has the opposite effect on those two phases.

The water molecules are actually closer together in the liquid phase than they are in the solid phase. Hopefully, these examples will help you in understanding the phase of water.
