Energy vs. temperature

Fig. 12. Free energy vs. temperature for FCC-cttrve /, for ECC-curve II and for the amorphous state (melt)-cur-ve III. Points 1 and 2 represent the melting temperatures of FCC and ECC, respectively, point 3 separates the ranges of the predominant existence of FCC and ECC (see text)...

Fig. 2.1 Energy vs temperature curves for two polymorphs I and II. A is the Hehnholz free energy and E is the internal energy. Consistent with the labelling scheme proposed by McCrone (see Chapter 1) Form I is assumed to be the stable form at room temperature. (From Buerger 1951, with permission.)...

A typical energy vs temperature diagram using the Gibbs relationship is given in Fig. 2.3. Compared to the analogous Fig. 2.1 there are two additional isobars the //liq curve (above the two (Hi and Hn) solid curves), and the Gnq curve. The H vs temperature curves may be constructed experimentally by determination of the heat capacity Cp, from... 

Fig. 2.3 Energy vs temperature (E/T) diagram of a dimorphic system. G is the Gibbs free energy and H is the enthalpy. This diagram represents the situation for an enantiotropic system, in which Form I is the stable form below the transition point, and presumably at room temperature, consistent with the labelling scheme for polymorphs proposed by McCrone (see Chapter 1). (Adapted from Grunenberg et al. 1996, with permission.)...

Fig. 2.5 Energy vs temperature (E/T) diagram for a monotropic dimorphic system. The symbols have the same meaning as in Fig. 2.3. Form I is more stable at all temperatures the crossing of the Gj and Gu curves (not shown) will be above the melting point for Form I and Form II. (From Grunenberg et al. 1996, with permission.)...

Figure la. Schematic plot of free energies vs. temperature for a scheme that does not show a mesophase. G., G and G, are, respectively, the free energies of the crystalline, mesomorphic (virtual) and Isotropic liquid states. T.. = T Is the crystalline melting point. Here, as In subsequent Figures lb and lc, the heaviest lines correspond to the stablest state at a given temperature. 

Figure lb. Schematic plot of free energies vs. temperature for the system In Figure 1 but with G, raised (to G ) so as to "uncover" the mesophase. an< are the crystal-mesophase transition and the lsotroplzatlon transition temperatures. 

Figure 6 Energy vs. temperature calculated using graph invariant theoiy for a) the ice VII-Vlll, b) Ih-XI, c) Vl-Vl and d) V-XIII systems. Upward and downward triangles indicate results of Metropolis Monte Carlo simulations ascending and descending in tempemture. The dashed line in panel (a) indicates the transition point established by thermodynamic integration. The arrows indicate experimental transition temperatures (not well established for the IIl-lX system).
