A handy of free and printable phase diagrams have been prepared for you in high definition! When you are learning phase in physics, a phase diagram is a must to help you understand the phase. A phase diagram especially in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, volume, etc.) at which thermodynamically distinct phases occur and coexist at equilibrium. Look at the following diagram.

Common components of a phase diagram are lines of equilibrium or phase boundaries, which refer to lines that mark conditions under which multiple phases can coexist at equilibrium. Phase transitions occur along lines of equilibrium. Phase diagrams illustrate the variations between the states of matter of elements or compounds as they relate to pressure and temperatures. The following diagrams an example of a phase diagram for a generic single-component system.



The figures above shows examples of several phase diagram, which summarizes the effect of temperature and pressure on a substance in a closed container. 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 points along the line connecting points A and B in the phase diagram in the figure above represent all combinations of temperature and pressure at which the solid is in equilibrium with the gas. At these temperatures and pressures, the rate at which the solid sublimes to form a gas is equal to the rate at which the gas condenses to form a solid.
