| Abstract: | High-temperature and high-pressure shock-wave data on fluids (pure species) have been combined with low-temperature and low-pressure data to generate a “corresponding state” equation in the virial format in reduced pressure and temperature for many species. The equation is then modified to obtain a similar equation of state for H2O. The fugacities of the pure species in the CHO system can be calculated to a temperature of 3000 K and to a pressure of 1 megabar. However, dissociation of the pure species may invalidate the data over certain pressure-temperature ranges. |
