Phase diagrams are one of the most important sources of information concerning the behavior of elements, compounds and solutions. They provide us with the knowledge of phase composition and phase stability as a function of temperature (T), pressure (P) and composition (C).

A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium.
13 kwi 2022 · If we know \(p\A^*\) and \(p\B^*\) as functions of \(T\), we can use Eqs. 13.2.6 and 13.2.7 to calculate the compositions for any combination of \(T\) and \(p\) at which the liquid and gas phases can coexist, and thus construct a pressure–composition or temperature–composition phase diagram.
12 lip 2023 · The Phase Diagram of Water. Figure \(\PageIndex{2}\) shows the phase diagram of water and illustrates that the triple point of water occurs at 0.01°C and 0.00604 atm (4.59 mmHg).
We see how to use phase diagrams to judge whether two substances are mutually miscible, whether an equilibrium can exist over a range of conditions, or whether the system must be brought to a definite pressure, temperature, and composition before equilibrium can be established.
The phase diagram of water illustrates the relationship between temperature, pressure, and the physical states of water: solid, liquid, and gas. At low temperatures and high pressures, water exists as a solid (ice), while at higher temperatures and lower pressures, it exists as a gas (water vapor).
We can use the phase diagram to identify the physical state of a sample of water under specified conditions of pressure and temperature. For example, a pressure of 50 kPa and a temperature of −10 °C correspond to the region of the diagram labeled “ice.”
