This model is thus a simplified representation of a semiflexible polymer in solution. In this phase diagram it should be noted that both phase transitions are second-order except for the coil to crystal transition for eg/e Ͼ 13, which is a first order one.

As shown, with increasing pressure the phase having the smaller molar volume will be stabilized. This transformation is * The configurational entropy of a frozen liquid approaches that of a crystal at a temperature denoted the Kauzmann temperature, after Kauzmann who first noted this fact. ** A negative entropy of solution in water implies an ordering of the water molecules adjacent to the polymer due to an interaction between them. e. a coil configuration. 3. The dependence of Gibbs free energy G, on pressure P.

Long-range order parameter as a function of reduced temperature in the Bragg–Williams model. D. Fast, Entropy, Philips Technical Library, 1962 with permission. Monte Carlo method merely provides a configuration for this model to evaluate. In effect, this statement is valid for all the methods used in treating the order– disorder transition. Hence, let us consider methods for evaluating the energies of a disordered phase. Many first-principle-based approximations for the energy of disordered solid solutions of alloy phases have been used in the past.
