fluctuation theorem for entropy production during effusion of a relativistic Ideal Gas
Physical Review E, 2008Co-Authors: Bart Cleuren, K Willaert, A Engel, C Van Den BroeckAbstract:The probability distribution of the entropy production for the effusion of a relativistic Ideal Gas is calculated explicitly. This result is then extended to include particle and antiparticle pair production and annihilation. In both cases, the fluctuation theorem is verified.

fluctuation theorem for entropy production during effusion of an Ideal Gas with momentum transfer
Physical Review E, 2007Co-Authors: Kevin B Wood, C Van Den Broeck, Ryoichi Kawai, Katja LindenbergAbstract:We derive an exact expression for entropy production during effusion of an Ideal Gas driven by momentum transfer in addition to energy and particle flux. Following the treatment in Cleuren et al. [Phys. Rev. E 74, 021117 (2006)], we construct a master equation formulation of the process and explicitly verify the thermodynamic fluctuation theorem, thereby directly exhibiting its extended applicability to particle flows and hence to hydrodynamic systems.

the gibbs duhem equation the Ideal Gas mixture and a generalized interpretation of dalton s law
Industrial & Engineering Chemistry Research, 2011Co-Authors: R RaviAbstract:The ideas used by Gibbs in defining the Ideal Gas mixture are brought to light in view of their fundamental significance and the fact that they have not received due attention in the literature. Specifically, the central role played by the well-known Gibbs−Duhem equation in this regard is explained. The concept of a fundamental equation and its importance in the definition of an Ideal Gas as well as an Ideal Gas mixture is elucidated. The manner in which these ideas enabled Gibbs to give a very general interpretation of Dalton’s law is examined in detail.

definitive Ideal Gas thermochemical functions of the h216o molecule
Journal of Physical and Chemical Reference Data, 2016Co-Authors: Tibor Furtenbacher, Aa Kyuberis, Nf Zobov, Ol Polyansky, Tamas Szidarovszky, Jan Hrubý, Jonathan Tennyson, Ag CsászárAbstract:A much improved temperature-dependent Ideal-Gas internal partition function, Qint(T), of the H216O molecule is reported for temperatures between 0 and 6000 K. Determination of Qint(T) is principally based on the direct summation technique involving all accurate experimental energy levels known for H216O (almost 20 000 rovibrational energies including an almost complete list up to a relative energy of 7500 cm−1), augmented with a less accurate but complete list of first-principles computed rovibrational energy levels up to the first dissociation limit, about 41 000 cm−1 (the latter list includes close to one million bound rovibrational energy levels up to J = 69, where J is the rotational quantum number). Partition functions are developed for ortho- and para-H216O as well as for their equilibrium mixture. Unbound rovibrational states of H216O above the first dissociation limit are considered using an approximate model treatment. The effect of the excited electronic states on the thermochemical functions is...

Definitive Ideal-Gas Thermochemical Functions of the H216O Molecule
2016Co-Authors: Furtenbacher T, Szidarovszky T, Hruby J, Aa Kyuberis, Nf Zobov, Ol Polyansky, Tennyson J, Ag CsászárAbstract:A much improved temperature-dependent Ideal-Gas internal partition function, Qint(T), of the H216O molecule is reported for temperatures between 0 and 6000 K. Determination of Qint(T) is principally based on the direct summation technique involving all accurate experimental energy levels known for H216O (almost 20 000 rovibrational energies including an almost complete list up to a relative energy of 7500 cm−1), augmented with a less accurate but complete list of first-principles computed rovibrational energy levels up to the first dissociation limit, about 41 000 cm−1 (the latter list includes close to one million bound rovibrational energy levels up to J = 69, where J is the rotational quantum number). Partition functions are developed for ortho- and para-H216O as well as for their equilibrium mixture. Unbound rovibrational states of H216O above the first dissociation limit are considered using an approximate model treatment. The effect of the excited electronic states on the thermochemical functions is neglected, as their contribution to the thermochemical functions is negligible even at the highest temperatures considered. Based on the high-accuracy Qint(T) and its first two moments, definitive results, in 1 K increments, are obtained for the following thermochemical functions: Gibbs energy, enthalpy, entropy, and isobaric heat capacity. Reliable uncertainties (approximately two standard deviations) are estimated as a function of temperature for each quantity determined. These uncertainties emphasize that the present results are the most accurate Ideal-Gas thermochemical functions ever produced for H216O. It is recommended that the new value determined for the standard molar enthalpy increment at 298.15 K, 9.904 04 ± 0.000 01 kJ mol−1, should replace the old CODATA datum, 9.905 ± 0.005 kJ mol−1
