Abstract : Tabular values of density, internal energy, enthalpy, and entropy of liquid and gaseous argon are presented for temperature from 83.8 to 300 K at pressures of 0.01 to 1000 atmospheres. Diagrams of specific heats, compressibility factor, and enthropy are included. The properties presented are calculated from an equation of state which was fitted to experimental P-p-T data from the world literature. Extensive comparisons were made between the equation of state and the experimental data, and deviation plots are presented. The second virial coefficient and Joule Thomson inversion curve were also calculated and comparisons made with values from other sources. A vapor pressure equation which covers the range from the triple point to the critical point is also given. (Author)
