A theory of gas solubility in water has been developed using the scaled-particle theory to calculate the reversible work required to introduce a solute molecule into a fluid. It yields very good agreement with experiment for the heats, entropies, and molar heat capacities of solution and for the partial molar volumes of the solutes. The "abnormal" thermodynamic properties of aqueous solutions are discussed in light of the enthalpy and entropy of cavity formation. The theory shows promise as a method for investigating the thermodynamic properties of aqueous solutions of ions and the properties of gas solubility in molten salts and molten metals. The theory has been used to determine the Lennard-Jones (6-12) pair potential parameters for water and for benzene. The values for water are = 2.76 A.
