An Amendment to the Second Law
Journal of Non-Equilibrium Thermodynamics, 1996The authors propose a precise statement of the second law of thermodynamics -- as used in continuum thermodynamics -- which includes an ``amendment'' (expression used by the authors) in order to systematically rule out solutions of the balance equations which do not satisfy the second law.

The thesis of this article is that thermodynamics is a rigorous science, and that the first law and the second law can be stated in an unambiguous and general way so that their implications are concrete and valid for both equilibrium and nonequilibrium states. In this light, we summarize the principles of thermodynamics, and introduce a graphical tool,

The Second Law of Thermodynamics and the Heart
Future Cardiology, 2012The second law of thermodynamics explains the phenomenon of irreversibility and the increasing entropic trend of nature. Similar to human-made machines, living structures are subjected to entropy generation, becoming 'worn' and 'damaged' from use. However, they have the possibility of eluding or deferring these processes.

Abstract Why are so many large-scale processes irreversible, happening in one direction but not the other as time passes? This chapter answers that question using three simple model systems: a collection of two-state particles such as flipped coins or elementary magnetic dipoles; the Einstein model of a solid as a collection of identical

In our study till now, we established the first law of thermodynamics, in which we saw that heat and work are equivalent insofar as they are different manifestations of the energy exchange between a system and its surroundings (or between various parts of a system). However, in this development, an asymmetry between heat and work has remained.

Second thoughts on the second law
European Journal of Physics, 1999Summary: An idea of an approach to the second law of thermodynamics in the introductory physics course is sketched, that only changes some accents in the traditional thermodynamic approach to expose some inappropriate views.

The second law of thermodynamics
1991The first law of thermodynamics was developed in Chapter 4 from a study of the effects of adiabatic work on the state of a system. This law introduces the concept of internal energy (a non-primitive state function) and imposes certain limitations on the changes that can occur in a system under given constraints.

GRAVITATION AND THE SECOND LAW OF THERMODYNAMICS
International Journal of Modern Physics D, 2004Just as gravitons can carry energy, they can also be used to transmit information. It follows that an entropy should be associated with gravitational degrees of freedom, independent of the presence or absence of black holes. In this essay, we discuss how one might count gravitational entropy given a classical gravitational field.

Much of the formulation of the first law of thermodynamics has been based on empirical observations of conversion of work into heat energy. But the reader needs to be cautioned that the insignia of the first law as displayed in (3.7) is not an ordinary mathematical equation because it does not guarantee that the reverse – i.e., the conversion of heat ...
