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.

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 ...

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.

It is common experience that watches run down, bouncing balls stop bouncing, and even the most perfectly designed and crafted engine will eventually cease operating. This universal tendency toward stasis is the essence of the second law of thermodynamics.

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.

Abstract The last thing Newton would have wished to be known as was a revolutionary. He was not to know, nor could he have guessed, that his second law of motion would help to change the intellectual atmosphere of Europe.

Discussion on “The Second Law and Energy”
AIP Conference Proceedings, 2008This article reports an open discussion that took place during the Keenan Symposium “Meeting the Entropy Challenge” (held in Cambridge, Massachusetts, on October 5, 2007) following the short presentations—each reported as a separate article in the present volume—by Thomas Widmer, Ernest Geskin, James Keck, Noam Lior, Debjyoti Banerjee, Richard Peterson,

Life and the Second Law of Thermodynamics
Nature, 1946WHETHER life processes obey the second law of thermodynamics or if life finds a way of evading the otherwise universal dissipation of energy has been something of a puzzle for a century. Kelvin left the matter open in his formulation of the Second Law, by expressly excluding the operations of ‘animate agencies’.
