The explosion heat (constant volume) of pentaerythritol trinitrate is 5271.8 J/g with liquid water. The specific volume is 967 ml/g and explosion temperature is 3,500 K. The lead-block value is 480 mL. The heat coefiftcient is 2824.2 J/g and the detonation coefficient is 49.91 J/g. The coefficient of specific coefficient is 9.661 L/kg. The detonation velocity of pentaerythritol trinitrate in an open vessel with a diameter of 30 mm is listed in Table 5.55. 

Solution No. Equation fq-ial applies to a specific path (constant-volume for Cv, constant-pressure for Cp). Once the path is specified, the amount of heat that is exchanged (jdQ) is uniquely defined and depends on the local state of the system. It is best to view eqs. and (t-iSi as the definitions of the heat capacities because they make clear that both Cv and Cp are state functions.

Fluctuations of observables from their average values, unless the observables are constants of motion, are especially important, since they are related to the response fiinctions of the system. For example, the constant volume specific heat of a fluid is a response function related to the fluctuations in the energy of a system at constant N, V and T, where A is the number of particles in a volume V at temperature T. Similarly, fluctuations in the number density (p = N/V) of an open system at constant p, V and T, where p is the chemical potential, are related to the isothemial compressibility iCp which is another response fiinction. Temperature-dependent fluctuations characterize the dynamic equilibrium of themiodynamic systems, in contrast to the equilibrium of purely mechanical bodies in which fluctuations are absent.

The dielectric constants of amino acid solutions are very high. Thek ionic dipolar structures confer special vibrational spectra (Raman, k), as well as characteristic properties (specific volumes, specific heats, electrostriction) (34). 

Available data on the thermodynamic and transport properties of carbon dioxide have been reviewed and tables compiled giving specific volume, enthalpy, and entropy values for carbon dioxide at temperatures from 255 K to 1088 K and at pressures from atmospheric to 27,600 kPa (4,000 psia). Diagrams of compressibiHty factor, specific heat at constant pressure, specific heat at constant volume, specific heat ratio, velocity of sound in carbon dioxide, viscosity, and thermal conductivity have also been prepared (5).

Specific heat of adsorbed phase at constant volume. 

The integrated terms are simply the specific heat of the unit mass of adsorbent and its associated adsorbate. The specific heat at constant volume has been used for the adsorbate since, theoretically, there is no expansion of the adsorbate volume and the heat required to raise the temperature is the change in internal energy. In practice there will be some expansion and a pessimistically high estimate could use the specific heat at constant pressure The specific heat of the adsorbed phase is in any case difficult to estimate and it is common to approximate it to that of saturated liquid adsorbate at the same temperature.
