Model Relating to Van Der Waals' Law in Thermodynamics, by Richard P. Baker, Baker #249

Usage conditions apply
Johannes D. van der Waals (1837-1923), a Dutch teacher, university professor, and theoretical physicist, derived modifications of the law of thermodynamics to account for interactions between molecules of liquids and gases. His research would bring him the Nobel Prize in physics in 1910. In this model, Richard P. Baker, a member of the mathematics department at the University of Iowa, plotted the thermal properties of a substance following van der Waals’s theory.
A tag on the model reads: No. 249 (/) Van der Waals' law
This is one of several models of thermodynamic surfaces made by Baker.
