Phase Diagrams

Normal: Occurs at 1 atm.

Critical Point: A combination of temperature and pressure beyond which a gas cannot be liquified.

• Critical Temperature: The temperature beyond which a gas cannot be liquified regardless of the pressure.

• Critical Pressure: The pressure beyond which a liquid cannot be vaporized regardless of the temperature.

Supercritical Fluid: A state of matter beyond the critical point that is neither liquid nor gas.

Triple Point: A point at which three phases coexist in equilibrium.
