Question
The Fisher–Widom and Frenkel lines can originate either at this point or next to it. Near this point, the size of density fluctuations increases due to the correlation length diverging, resulting in a namesake form of opalescence. Newton’s correction is used when the van Der Waals equation is applied to this point, where it predicts a compressibility factor of three-eighths. For water, this point occurs at 647 kelvin. The enthalpy of vaporization becomes zero at this point, which is the endpoint of the liquid-vapor coexistence curve. For 10 points, name this point on a phase diagram where the solid and liquid phases become indistinguishable. ■END■
ANSWER: critical point [accept critical opalescence]
