The critical point is a temperature and pressure at which the properties of the liquid and gas phases become identical, and the distinction between the two phases disappears. Above the critical point, there is no distinction between liquid and gas, and the substance is called a supercritical fluid. The critical point is important in many scientific and industrial applications, such as in the production of supercritical fluids for use as solvents in chemical reactions or as a power source in turbines.
Critical points are not limited to liquids and gases and can occur in various systems, including solids and even living organisms. For example, critical points can be found in magnets and superconductors,
