Thermodynamic Properties. Low temperature heat capacity and entropy data on MoS2 have been developed61. The heat capacity exhibits approximately T2 dependence between 20 and 60 K. For MoS2 (c), an entropy of S°298 = 14.96 0.02 cal deg-1 mole-1 has been reported62. The values for the heat of formation, AH°= —56.1 kcals/mole, and for the free energy of formation, AG° = —54.1 kcals/mole, have been calculated63. ... [Pg.74]

Thermal analysis is capable of providing accurate information on the phase transition temperatures, degradation temperatures, heat capacity, and enthalpy of transition of polymers using comparatively simple DTA, DSC, and TG instruments. The measurement time is short compared with other techniques, such as viscoelastic measurement and nuclear magnetic resonance spectroscopy. Moreover, any kind of material, e.g., powders, flakes, films, fibers, and liquids, may be used. The required amount of sample is small, normally in the range of several milligrams. [Pg.213]

It is necessary to specify zero ionic strength here because Debye-HUckel adjustments for ionic strength depend on the temperature. Heat capacities and transformed heat capacities are discussed in an Appendix to this chapter. However, since there is not very much information in the literature on heat capacities of species or transformed heat capacities of reactants, the treatments described here are based on the assumption that heat capacities of species are equal to zero. When molar heat capacities of species can be taken as zero, both standard enthalpies of formation and standard entropies of formation of species are independent of temperature. When Af H° and Af 5° are independent of temperature, standard Gibbs energies of formation of species at zero ionic strength can be calculated using... [Pg.72]

Nellson and White (8) have measured the low temperature heat capacity and heat of vaporization and have reported an entropy in the gas phase at 232.5 K of 63.919 0.28 cal K mol . This compares with 63.959 cal K mol calculated from our adopted functions. [Pg.579]

Moore (8) measured high temperature enthalpy data from 670.5 to 941 K by drop calorimetry. The low temperature heat capacities and high temperature enthalpy data were smoothly joined at 298.15 K. The C values above 941 K were obtained by graphical extrapolation. Getting and Gregory ( ) measured high temperature heat capacities in the temperature range from 60 to... [Pg.798]

The low temperature heat capacity and entropy of copper have been well established by the critical review of Furukawa et al. ( ). Their recommended smoothed values are adopted with minor corrections for a change in the relative atomic mass from 63.54 to 63.546 (2) and for a change to the International Practical Temperature Scale of 1968 (3). These corrections tncrease the entropy at 298.15 K from 7.923 to 7.928 cal K" mol" and the enthalpy difference, H (298.15 K) - H (0 K), from 1.1962 to 1.1967 kcal mol". The values recommended by CODATA (4) are those of Furukawa (1 ). [Pg.970]

The structural parameters were taken from the electron diffraction measurements of Smith and Hedberg (5). The vibrational frequencies are those chosen by Hitsatsune et al. (6). The torsional frequency of 50 cm" was estimated in order to bring the entropy of the gas into agreement with that determined by Giauque and Kemp (1 ) from low temperature heat capacities and heats of... [Pg.1560]

High temperature studies are summarized below along with the pertinent low temperatures studies. The selected heat capacities above 300 K are obtained from a Shomate plot of the adopted low temperature heat capacities and the enthalpies reported or derived from the work of Dennison (5), Kantor et al. (6), Olette (7), Serebrennikov and Gel d (8) and Magnus (9). [Pg.1796]

The choice of environmentally benign refrigerant, e.g. CO2, NH3, hydrocarbons, its physical properties (liquifaction temperature, heat capacity) and the compressor unit determine the effieiency of these driers and the temperature range over which they operate most operate at 40-50°C but some can work efficiently up to 80°C. [Pg.280]
