The perfect gas equation, laws, principles and processes as well as the van der Waals equation for real gases are represented geometrically. Intensive and extensive properties and the standard temperature and pressure (STP) condition are shown too. Plane geometry offers a supplementary method to the piston formulation for explaining and visualizing gas properties. Several difficulties and misconceptions of students may thus be resolved.
