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

open access: yesEntropy, 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 ...

The Second Law of Thermodynamics as a Force Law [PDF]

open access: yesEntropy, 2018
The second law of thermodynamics states the increase of entropy, Δ S > 0 , for real processes from state A to state B at constant energy from chemistry over biological life and engines to cosmic events.

Thermoelectric Cycle and the Second Law of Thermodynamics [PDF]

open access: yesEntropy, 2023
In 2019, Schilling et al. claimed that they achieved the supercooling of a body without external intervention in their thermoelectric experiments, thus arguing that the second law of thermodynamics was bent.

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.

Helping Pregraduate Students Reach Deep Understanding of the Second Law of Thermodynamics

open access: yesEducation Sciences, 2021
Pregraduate students often have low success expectations toward their thermodynamics courses, which are often considered too abstract and remarkably difficult to understand. For this reason, they may not even try to reach any level of comprehension while

Infrared Cloaking, Stealth, and the Second Law of Thermodynamics

open access: yesEntropy, 2012
Infrared signature management (IRSM) has been a primary aeronautical concern for over 50 years. Most strategies and technologies are limited by the second law of thermodynamics.

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?

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 ...
