**Gibbs' Paradox Physics Forums**

This leads to a paradox known as the Gibbs paradox , after Josiah Willard Gibbs. The paradox allows for the entropy of closed systems to decrease, violating the second law of thermodynamics . A related paradox is the "mixing paradox".... For entropy of mixing to exist, the putatively mixing molecular species must be chemically or physically detectably distinct. Thus arises the so-called Gibbs paradox , as follows. If molecular species are identical, there is no entropy change on mixing them, because, defined in thermodynamic terms, there is no mass transfer , and thus no thermodynamically recognized process of mixing.

The entropy of mixing (also known as configurational entropy) is the change in the entropy, an extensive thermodynamic quantity, when two different chemical substances or components are mixed.... This leads to a paradox known as the Gibbs paradox , after Josiah Willard Gibbs. The paradox allows for the entropy of closed systems to decrease, violating the second law of thermodynamics . A related paradox is the "mixing paradox".

The paradox is that the two gases can be arbitrarily similar, but the entropy from mixing does not disappear unless they are the same gas. The resolution is provided by a careful understanding of entropy.... J. W. Gibbs- arguably the frist great American scientist who combined the concepts of heat and entropy and proposed “[Gibbs] Free Energy”, G , a thermodynamic state function

For entropy of mixing to exist, the putatively mixing molecular species must be chemically or physically detectably distinct. Thus arises the so-called Gibbs paradox, as follows.

### The entropy of mixing ideal gases was treated already by Gibbs. The result is known as the Gibbs’ paradox. Several scientists were engaged with this paradox, among them Rayleigh, Lorentz, Einstein, and von Neumann 1 [1,2].

- Gibbs paradox: revisited Term paper prepared by Ganga P Purja Pun CSI 612 Spring 2005 1. Introduction The Gibbs paradox is about entropy of mixing gases.
- However, the above process is not the Gibbs paradox. The Gibbs paradox can refer to one of two things: The Gibbs paradox can refer to one of two things: erroneous predictions of giant mixing entropies from mistreating indistinguishable particles as distinguishable (and vice versa), as …
- Put another way, as Gibbs noted, the entropy of the gases was not extensive in the classical picture. Unlike, say, mass, the total entropy of the mixed system is not simply the sum of the entropy of the unmixed volumes of gas.
