WebIn thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. One example is the liquid–vapor critical point, the end point of the pressure–temperature curve that designates conditions under which a liquid and its vapor can coexist. At higher temperatures, the gas cannot be liquefied by pressure alone. WebOct 9, 2015 · 2 Answers. Sorted by: 3. Critical points refer to the first derivative.

WebFeb 11, 2024 · The critical point is the point at which the critical pressure (P CR) and the critical temperature (T CR) converge on the graph together. As such, it can also be seen as the point at which the phase equilibrium curve between liquids and gasses ends. Once these two values intersect and form the critical point, there is an important shift.
