In addition, the occurrence of a critical point in the gas-liquid phase transition clearly suggests the absence of essential differences between the liquid and gaseous state. 5 2 3 4 5 6 7 Vr = VIVc 8 9 Fig. 5. 7K). cp = critical point.

0g/ml) and hence its characteristic dissolving power. Finally, an SF can also be defined as a heavy gas with a controllable dissolving power or as a form of matter in which the liquid and gaseous state are indistinguishable. g. that in Fig. 1) shows the temperature and pressure regions where the substance occurs as a single phase [viz. solid (s), liquid (I) or gaseous (g)]. Such regions are bounded by curves indicating the coexistence of two phases (s-g, s-l and l-g, which are involved in sublimation, melting and vaporization equilibria, respectively).
