Use of the van der Waals equation of state to calculate molar volume and compressibility factor for a gas.
Solution of a single nonlinear algebraic equation.
The ideal gas law can represent the pressure-volume-temperature (PVT) relationship of gases only at low (near atmospheric) pressures. For higher pressures, more complex equations of state should be used. The calculation of the molar volume and the compressibility factor using complex equations of state typically requires a numerical solution when the pressure and temperature are specified.
