Abstract
New measurements of the molar volume of (0.476Ar + 0.524N2)(1) at the temperature 119.33 K and at pressures from close to the vapour pressure up to 145 MPa are reported in this work. They were used, together with results from other authors, to fit parameters for the cross intermolecular potential, in the framework of the van der Waals one-fluid model. Using the same procedure for the binaries (oxygen + nitrogen) and (argon + oxygen) molar volumes and molar residual enthalpies of liquid air were then calculated for pressures up to 80 MPa and compared with correlation results.
