Thermodynamic properties such as density, vapor pressure, heat of evaporation, and the speed of sound for three pure reference fluids were computed applying various common equations of state over a fairly wide range of pressures and temperatures. The results obtained by rather basic equations of state were held against those from sophisticated reference equations, and contour plots were drawn indicating the respective error margins. Thereby, it was quantitatively illustrated within which limits cubic equations of state can be used for reasonably accurate calculations of various properties.
