What is Critical Point

1.

Critical point is the end point of liquid-vapor coexistence line. The properties of liquid and vapor become identical in the critical point. Learn more in: High-Power Heat Transfer in Supercritical Fluids: Microscale Times and Sizes

2.

The point where the distinction between the liquid and gas phases disappears, i.e., both phases has the same temperature, pressure, and volume. The critical point could also be called as critical state. Learn more in: The Basic Thermal Hydraulic Issues of Applying Supercritical Fluid to Nuclear Reactors

3.

A critical point is a point on an obstacle at which two parallel explorer robot, moving in the same lateral speed, unable to view each other due to the presence of that obstacle. Learn more in: Techniques in Multi-Robot Area Coverage: A Comparative Survey

4.

The point where boundary between gas and liquid phase merges, and above which point (temperature and pressure condition) there is no phase change happen between the two phases. Learn more in: Thermal-Mechanical Effects and Near-Critical Fluid Dynamic Behaviors in Micro-Scale

5.

(also called a critical state) is the point in which the distinction between the liquid and gas (or vapour) phases disappears, i.e., both phases have the same temperature, pressure and specific volume or density. The critical point is characterized with the phase-state parameters: T cr , P cr and v cr (or ? cr ), which have unique values for each pure substance.
