Simplified Gas State Equations at Saturation and Isotherm.

ABSTRACT: This paper further simplifies the gas state equation (EOS) by introducing a thermodynamic constant, P _c ^*, into the equation, a theoretical pressure that all gas converts into liquid. In the gas-liquid saturation system, linear regressions of ln P-ln x ₂ from M.P. to T _c give P = P _c ^* x ₂. It verifies Henry's law of gas solubility. Meanwhile, P _c ^*s for most substances are found in the range of 15-16, i.e., 3.269-8.886 MPa. Hence, EOS deforms into . Isotherm is a forced equilibrium system sustained by an outer force. Isothermal EOS is derived by differentiating heat over V _G. , where or . Empolying Ar as an example, EO
