SUMMARY
The Maxwell construction is a method used to determine phase equilibrium in the inhomogeneous regions of van der Waals isotherms, where the system is spatially homogeneous but contains unstable regions that separate into fluid and gaseous phases. It is essential for ensuring that the chemical potentials of the liquid and gas phases are equal, which is achieved by balancing the signed areas under the curve of the pressure-volume relationship. This technique is distinct from Maxwell relations and is crucial for understanding phase transitions in thermodynamics.
