  4. Abstract:
  5. Regularities shown by different fluids along the contour of the ideal compressibility factor Z= PV/(RT)=1 in the temperature density plane was used to test the accuracy of the equations of state and derive temperature dependencies of their parameters. The contour, also known as the Zeno line, was empirically observed to be nearly linear. The precision of the van der Waals equation in predicting the Zeno line was evaluated. It was shown that the equation could predict a linear relation between temperature and density on the Z=1 contour, qualitatively
