Abstract
Thermophysical properties of methane are tabulated at uniform temperatures from 90.68 to 500 K along isobars to 700 bar. A novel equation of state is employed for the first time, having origin on the vapor-liquid coexistence boundary. Computations are based almost entirely on ideal gas specific heats and experimental P-rho-T data via the equation of state, without weighting to data for derived properties. Good agreement with such data confirms validity of the equation and method. New P-rho-T data are reported at 0.3 to 1.7 times the critical density.Keywords
