What Is the Real Clausius Statement of the Second Law of Thermodynamics? [PDF]

open access: yesEntropy (Basel), 2019
In this paper, we first analyze the difference between the second law of thermodynamics and the laws in other disciplines. There are some phenomena in other disciplines similar to the Clausius Statement of the second law, but none of them has been ...

Thermodynamics in Rastall gravity with entropy corrections

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We explore the thermodynamic analysis at the apparent horizon in the framework of Rastall theory of gravity. We take different entropies such as the Bakenstein, logarithmic corrected, power law corrected, and the Renyi entropies. We investigate the first

Modeling Fluid dynamics and Aerodynamics by Second Law and Bejan Number (Part 1 - Theory) [PDF]

open access: yesINCAS Bulletin, 2019
Two fundamental questions are still open about the complex relation between fluid dynamics and thermodynamics. Is it possible (and convenient) to describe fluid dynamic in terms of second law based thermodynamic equations?

The Second Law and Entropy Misconceptions Demystified

open access: yesEntropy, 2020
The challenges and claims of hypothetical violations of the Second Law of thermodynamics have been a topic of many scientific, philosophical and social publications, even in the most prestigious scientific journals.

The second laws of quantum thermodynamics [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
Significance In ordinary thermodynamics, transitions are governed by a single quantity–the free energy. Its monotonicity is a formulation of the second law. Here, we find that the second law for microscopic or highly correlated systems takes on a very different form than it does at the macroscopic scale, imposing not just one constraint on ...

The Rectified Second Law of Thermodynamics [PDF]

open access: yesThe Journal of Physical Chemistry B, 2006
Equilibrium thermodynamics is combined with Jarzynski's irreversible work theorem to quantify the excess entropy produced by irreversible processes. The resulting rectified form of the second law parallels the first law, in the sense that it facilitates the experimental measurement of excess entropy changes resulting from irreversible work and heat ...

Antimatter and the Second Law of Thermodynamics [PDF]

open access: yesFoundations of Science, 2020
AbstractIn this short paper we make a proposal that the second law of thermodynamics holds true for a closed physical system consisting of pure antimatter in the thermodynamical limit, but in a reversed form. We give two plausible arguments in favour to this proposal: one refers to the CPT theorem of relativistic quantum field theories while the other ...
