The analysis

The claim describes the core definition and historical purpose of the Van der Waals equation of state in physics and chemistry (introducing parameters for finite molecular volume and attractive intermolecular forces to correct the ideal gas law). This is a textbook fact of basic science, making it common knowledge.
