Sample text

At least initially, one can assume that all of the quantum-mechanical systems are equivalent. Furthermore, they should all be in thermal contact, but otherwise be independent. The number of microscopic systems that are occupying level 1 with energy level ez is n~; the number with ee is he; the number with e 3 is n3; etc. The number of microscopic systems is, for simplicity, assumed to be the number of molecules, N. It is given by the sum over all n~. The value of N is directly known from the macroscopic description of the material through the chemical composition, mass, and Avogadro's number.

23. Heat capacity of polytetrafluoroethylene [21]. 2. Poly(oxybenzoate-co-oxynaphthoate) Fig. 24 represents an even more complicated polymer system. In this case the macromolecule is the random copolymer poly(oxybenzoate-co-oxynaphthoate), a high-strength material (VectraTM). The graph shows a rather small endotherm and a rather broad, possibly two-stage glass transition that stretches over more than 100 K. Without precise computation of the liquid and solid heat capacities, it would not have been possible to identify the glass transition and provide important characteristics for the practical application of the polymer.

Typical values for the Einstein temperatures OF. for Na, A1, B and C (diamond) are 150, 385, 1220, and 1450 K, respectively. These O-values correspond approximately to the heat capacity represented by curves 1 to 4 in Fig. 4. Elements with strong bonds are known as hard solids and have high O-temperatures; elements with weaker bonds are softer and have lower O-temperatures. Somewhat less obvious from the examples is that heavy atoms have lower O-temperatures than lighter ones. These correlations are easily proven by the standard calculations of frequencies of vibrators of different force constants and masses.
