Condições de equilíbrio termodinâmico: a função disponibilidade

open access: yesQuímica Nova, 2011
The thermodynamic equilibrium is a state defined by conditions which depend upon some characteristics of the system. It requires thermal, mechanical, chemical and phase equilibrium.

Mesoscopic non-equilibrium thermodynamics

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
Basic concepts like energy, heat, and temperature have acquired a precise meaning after the development of thermodynamics. Thermodynamics provides the basis for understanding how heat and work are related and with the general rules that the macroscopic ...

Can Quantum Correlations Lead to Violation of the Second Law of Thermodynamics?

open access: yesEntropy, 2021
Quantum entanglement can cause the efficiency of a heat engine to be greater than the efficiency of the Carnot cycle. However, this does not mean a violation of the second law of thermodynamics, since there is no local equilibrium for pure quantum states,

Thermodynamic Equilibrium in the Expanding Universe [PDF]

open access: yesGeneral Relativity and Gravitation, 1999
We show that a relativistic gas may be at ``global'' equilibrium in the expanding universe for any equation of state $0 < p \leq /3$, provided that the gas particles move under the influence of a self-interacting, effective one-particle force in between elastic binary collisions.

Contact Geometry of Mesoscopic Thermodynamics and Dynamics

open access: yesEntropy, 2014
The time evolution during which macroscopic systems reach thermodynamic equilibrium states proceeds as a continuous sequence of contact structure preserving transformations maximizing the entropy.
