A schematic of a pressure-temperature diagram for a fixed composition mixture is shown in Figure 2.1. The phase representation of a mixture on a P P diagram is bivariant rather than univariant as in the case of a pure-component vapor pressure curve. At temperature Tj and pressure Pj, represented by point A, the mixture is... 

Figure 5 depicts the liquid spinodal curves Sp(L) in a pressure-temperature diagram for fixed CO2 compositions. The region of negative pressures, which is of interest for describing the capillary properties of CO2 aqueous solutions, has been also included. Interestingly, it can be noted that spinodal Sp(L) isopleths present a pressure-temperature trend, which looks similar to the liquid spinodal curve of pure water.At low temperatures, the Sp(L) isopleths are decreasing steeply before to reach a pressure minimum. Then at subcritical temperatures, isopleths are less spaced and sloped, and they finish to meet the H2O-CO2 critical curve. The temperature appears as a determining parameter in the explosivity control of CO2 aqueous solutions. Like for water, the easiest way to generate an explosive vaporization is a sudden depressurization in the superspinodal domain, where spinodal curves have a gentle slope in a P-T diagram (Fig. 5). This superspinodal field can be estimated theoretically irom the PRSV equation of...

The theory of sublimation will become clear by reference to Figure 2.7, which is the vapour pressure-temperature diagram for camphor. The vapour pressure of a solid increases with temperature in much the same way that the vapour pressure of a liquid does. 

As an example, consider the system formed by liquid water in equilibrium with its own vapor. The pressure—temperature diagram for this system has been constructed over the range of 1-99°C [10] and is shown in Fig. 1. The characteristics of a univariant system (one degree of freedom) are evident in that for each definite temperature value, water exhibits a fixed and definite pressure value.
