Help your study on phase diagrams with these examples of phase diagrams. More reference, more fruitful information. These diagrams include the phase of water and critical point diagram.
A phase diagram is a type of chart used to show conditions (pressure, temperature, volume, etc.) at which thermodynamically distinct phases occur and coexist at equilibrium. Every point in this diagram represents a possible combination of temperature and pressure for the system. The diagram is divided into three areas, which represent the solid, liquid, and gaseous states of the substance. The figure below shows an example of a phase diagram, which summarizes melting point.
A typical phase diagram has pressure on the y-axis and temperature on the x-axis. As we cross the lines or curves on the phase diagram, a phase change occurs. In addition, two states of the substance coexist in equilibrium on the lines or curves. Triple points are points on phase diagrams where lines of equilibrium intersect. Triple points mark conditions at which three different phases can coexist.
The phase diagram for water above is useful for learning how to analyze these diagrams. Along the blue phase boundary, water exists as both a vapor and a liquid. Along the dotted green phase boundary, we see the anomalous behavior of water: it exists as a solid at low-enough temperatures and high-enough pressures. At the triple point, water in the solid, liquid, and gaseous states coexist. All diagrams are available to be saved, just click on the image to enlarge and save it.
