Thermodynamics of internal strain in perfect crystals
Journal of Physics C: Solid State Physics, 1971The thermodynamic theory of solids is generalized to take explicit account of internal strains in perfect non-Bravais crystals. Treating external and internal strains as independent leads to the definition of generalized thermodynamic properties, namely elastic constants, heat capacities, thermal expansion coefficients and Gruneisen parameters ...

Thermodynamic perfect fluid. Its Rainich theory
Journal of Mathematical Physics, 1989The conditions for a relativistic perfect fluid to admit a thermodynamic scheme are considered, and the necessary and sufficient requirements for a metric to define a thermodynamic perfect fluid space-time are given.

The fundamental property of a perfect gas and the second law of thermodynamics
Archive for Rational Mechanics and Analysis, 1996This paper deals with the question of whether a proof of Clausius inequality can be given on the basis of a finite number of processes involving the union of an arbitrary system and a finite number of copies of a perfect gas, but avoiding the pass to the limit, which is neither mathematically nor physically admissible.

Thermodynamic Properties of Hypothetical Perfect and Real Krypton Crystals
Physica Status Solidi (a), 1971From measurements of the thermal expansivity and the isothermal compressibility at P = 0 of solid Kr using X-ray diffraction and a dilatometer between 4 and 115 K some vacancy properties could be determined. We found h = (86 ± 9) meV for the formation enthalpy of monovacancies, for the entropy, and for the vacancy free volume of formation atomic ...

Entropy: Part II — Thermodynamics and Perfect Order
Advanced Energy Systems, 1999Abstract Part II of this two-part paper refutes the beliefs about the statistical interpretation of thermodynamics, and the association of entropy with disorder that are summarized in Part I. The refutation of the statistical approach is based on either a nonstatistical unified quantum theory of mechanics and thermodynamics, or an almost

Thermodynamics of a dilute non-perfect Bose-Einstein gas
Europhysics Letters (EPL), 2000We study the thermodynamics of a dilute Bose gas. Not too close to the Bose-Einstein transition we find results differing from the ones in the literature. As a consequence the low momentum part of the distribution of quasiparticules is not a Bose factor, and the effective spectrum is not of the phonon type.
