Matter can be pushed to temperatures and pressures beyond those of its critical point. This stage is characterized by the inability to distinguish whether the matter is a liquid or a gas, as a result, Supercritical fluids (SCF) do not have a definite phase.

In a phase diagram, the critical point or critical state is the point at which two phases of a substance initially become indistinguishable … WebThe first root c 1 = 0 is not a critical point because the function is defined only for x > 0. Consider the second root: 2 ln c + 1 = 0, ⇒ ln c =−1 / 2, ⇒ c 2 = e −1/2 = 1 / √e. Hence, c 2 = 1 / √e is a critical point of the given function.
