How To Read A Phase Change Diagram This is a chemistry tutorial video that goes through how to read, analyze, and interpret a phase diagram. there are several examples of different questions y. Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. 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.

How To Interpret A Phase Change Diagram Phase diagram. a phase diagram represents the various physical states or phases of matter at different pressures and temperatures. in other words, it summarizes the effect of pressure and temperature on the nature of a substance. a phase diagram is divided into three areas representing the substances’ solid, liquid, and gaseous phases [1 4]. Three dimensional phase change diagrams plot three thermodynamic variables and show regions of space corresponding to different phases. in this type of diagram, we have a triple line instead of a triple point, and coexistence surfaces instead of coexistence curves. below is a generic 3d diagram plotting temperature, pressure, and specific volume. Learn how to interpret phase diagrams, which show how temperature and pressure affect the state of matter of a substance. khan academy offers free, interactive lessons on chemistry and more. Suppose you have a pure substance at three different sets of conditions of temperature and pressure corresponding to 1, 2 and 3 in the next diagram. under the set of conditions at 1 in the diagram, the substance would be a solid because it falls into that area of the phase diagram. at 2, it would be a liquid; and at 3, it would be a vapor (a gas).
