In conformal field theories, it is at this point the correlation length becomes infinite.
In conformal field theories, it is at this point the correlation length becomes infinite. At this point both the first and second derivatives of pressure with respect to volume are zero. At this point for a binary mixture, density fluctuations of increasing wavelength cause the mixture to become cloudy. A popular solvent used in decaffeination reactions is carbon dioxide pushed past this point, and at this point that the enthalpy of vaporization becomes (*) zero. This point, which occurs at 647 kelvin in water, is the endpoint of the liquid-gas boundary. For 10 points, name this point on a phase diagram at which a substance is neither a liquid or a gas, but a homogenous mixture of both.
In conformal field theories, it is at this point the correlation length becomes infinite.
