Title: Measurement and correlation of the (pressure, density, temperature) relation of argon II. Saturated-liquid and saturated-vapour densities and vapour pressures along the entire coexistence curve
Abstract: Comprehensive and accurate measurements of the saturated-liquid and saturated-vapour densities together with the vapour pressure of pure argon have been carried out from the temperature T = 84 K (triple-point temperature T1 = 83.8058 K) to about 0.04 K below the critical temperature. The critical constants (Tc = 150.687 K, ρc = 535.6 kg·m-3, pc = 4.863 MPa) and the isothermal compressibilities in the critical region close to the phase boundary were also determined from these measurements. Comparisons with experimental results of previous workers are presented. Based on the new values of this work, new correlation equations for the vapour pressure, the saturated-liquid density, and the saturated-vapour density have been established.
