equation of state
equation describing the state of matter under a given set of physical conditions
Debye model
mathematical model of a solid that treates the vibrations of the atomic lattice as phonons in a box
activity coefficient
value accounting for thermodynamic non-ideality of mixtures

thumb|250px|Saddle azeotrope calculated with UNIFAC at 1 atm. Red lines are vapor compositions and blue lines are liquid compositions. Image is rotating to more clearly show the saddle-like shape of the vapor–liquid equilibria
Lee-Kesler method
Method to estimate saturated vapor pressure
