The equation for heat capacity at constant volume (CV) can be written as Eq. (2.2). (2.2)Q=nCVΔT The equation of the first law of thermodynamics for an isochoric process (constant volume) has been reduced to Eq. (2.3). (2.3)Q=ΔU For monoatomic molecule By taking the value of ...
The k i's are determined by fitting the measured low-temperature heat capacity data. C' p is the departures from the 3Rn limit for some substances due to cation disordering, anharmonicity and electronic contributions. The five constants in the proposed equation were determined for six minerals ...
i. heat capacity, entropy and free energy of gaseous nitric oxide from near zero absolute to 5000°k.l Heat capacities, entropies, free energies, total energies and dissociation constants have been calculated for H2H2and for H1H2, to 3000°K, by reliable met... HL Johnston,AT Chapman 被...
The exact solution is given by an implicit equation 5/4(u-1)4+20/3(u-1)3+15(u-1)2+20(u-1)+51n(u-1) =u(u.t-x+x()), (14) where u and x0 are arbitrary constants. FINITE DIFFERENCE SCHEhfE 65 FIG. 1. Exact solution (-)...
The details concerning the evaluation of force constants and heat capacity from the density-of-states obtained from the dispersion curves are given in additional pub- lication by the authors. 22 EXPERIMENTAL The INS for poly(L-glutamic acid) was obtained at the AMMRC, Watertown slow chopper. ...
It appears that the kinetic metastability limit of the liquid (nucleation terminated) at both hot and cold extremes may be reached at the same value of the liquid heat capacity. 展开 关键词: Heat transfer Supercooling Mixtures Water Liquids Measurement Deuterium compounds Oxides Computations Value ...
