The relationships between the various forms of solid H2 O and solid-liquid H2 0 equilibria are well understood owing to the extensive work of P. W. Bridgman [1,2, 4, 5,6], These relationships are shown in Figure 16-1. Bridgman's [3] curve for solid-liquid equilibrium in CO2 is also shown in this figure. The specific volumes of water in cm3 /gm as a function of pressure and temperature are given in Table 16-1. The sources of these data are as follows: Table 16-2, the specific volumes of water at saturation, are taken from Osborne, Stimson, and Ginnings [18], Tilton and Taylor [22], and Owen, White, and Smith [19]. Table 16-3, the density, pressure, and temperature for CO2 are taken from Kennedy [13]. REFERENCES FOR SECTION 16 1. Bridgman, Proc. Am. Acad. 47, 441, 1911
