Gibbs's thermodynamic surface is the expression of the thermodynamic relationship between the entropy, volume and energy of a substance at varied temperature and pressure.[2] This thermodynamic expression is the basis of Maxwell's thermodynamic surface, a model that provides a three-dimensional plot of the various states of a fictitious substance with water-like properties. This plot has coordinates volume (x), entropy (y), and energy (z). [3]
