Fig. 1.5 The van der Waals isotherms for carbon dioxide (Tc = 304.14K) . When TTc, there is a region
AA'BB'C in which, for a given value of p, the van der Waals equation does not specify a unique volume
V ; in this region, the gas transforms to a liquid. The segment A'BB' is an unstable region; states
corresponding to points on this segment are not experimentally realizable. Experimentally realizable
states are on the segment ABC. A detailed description of this region is discussed in chapter 7.
