Talk:Thermodynamic potential

message: The person that added this to the top of the article should also have modified the parts of the text that talk about the four common thermodynamic potentials, because now there are five equations. Why don't we just list all the energy potentials? I think there are only eight of them.ChrisChiasson 12:47, 9 October 2007 (UTC)
replies: text: Also, it appears that the present form of the Landau potential does not take into account the possibility of multiple species (since it lists only one chemical potential). ChrisChiasson 06:46, 23 October 2007 (UTC)
thread_title: Landau Potential

message: Regarding the merging of of the thermodynamic potentials section from the thermodynamics page - I think a paragraph or two for someone wanting to get an overview is appropriate, then they can link to this main article for a more in-depth explanation. PAR 22:15, 8 November 2005 (UTC)
thread_title: Merging Overview

message: I removed the section that was added, because I think it was just pulled from the
thermodynamics article, and it doesn't fit.
* There are no "above differential forms"
* the notation using E has never been introduced
* thermodynamics stands more or less alone as a discipline, It does not need statistical mechanics to justify it or to derive any of its results, only to explain its results from a microscopic viewpoint.
* It is important not to get statistical mechanics and thermodynamics all jumbled up. Any discussion of this fact should go on the thermodynamics page. PAR 12:45, 29 November 2005 (UTC)

message: I think the statements this article makes about the second law might be wrong because there is no mention that the temperature in the first statement is the temperature of the surroundings and not the system. Flying Jazz 04:40, 3 January 2006 (UTC)
thread_title: Second Law error?

message: The introduction is good (especially when compared with other articles around this topic) but is weakened by the words "in a sense,".  For this sort of  article we need positive statements. If the author has reservations about this assertion we should at least be told what the other "senses" are.   
I move we remove the words "in a sense,".  It still stands as a correct and meaniningful statement. 
Overall the style is clear and is way ahead of the "entropy" articles which are long on jargon and short on clear defintions.   PAS 22:53, 27 February 2007 (UTC)
replies: text: I have modified the introduction and deleted the words "in a sense" but I have also made some other changes. In particular, I found the use of the word "parameters" and the associated link misleading. I understand this was meant to make it more accessible to the general public, but the word "function" is more correct and I think equally simple. I also added the important fact that all material properties at equilibrium could be derived from the potential (which is I think where the word "potential" comes from). Now, I am not a native speaker and I hope the sentences are not too clumsy. Tizeff 10:52, 28 October 2007 (UTC)
thread_title: Style of Introduction 

message: The entropy S(U,V,N) is also referred to as a thermodynamic potential. Not only the thermodynamic potential one get when performing a legendere transformation are thermodynamic potentials. I can provide a german theoretical physics book as reference: Grundkurs Theoretische Physik 4: Spezielle Relativitätstheorie, Thermodynamik page 230 et seqq. Maybe there is an english version of this book. --Biggerj1 (talk) 09:56, 30 July 2013 (UTC)
replies: text: This is a whole other can of worms. You can develop thermodynamic equations based on energy, in which case all thermo potentials have units of energy, and since entropy does not, it is not a thermodynamic potential in the energy development. I am not too familiar with the entropy development, but it may assume the role of a "potential" in that. PAR (talk) 07:29, 23 December 2019 (UTC)
thread_title:  S(U,V,N) 

message: I wonder if there is a need to include a negligible [gravitational potential energy] at the introduction. It seems to me it only makes it confusing without the need.

replies: text: It's not always negligible. In describing the density change of the atmosphere as a function of height, it is vital. PAR (talk) 07:24, 23 December 2019 (UTC)
thread_title:  Gravity 

message: It is incorrect to compare thermodinamic potentials with gravity or similar because gravity actually is the energy while thermodinamics potentials are mathematical definition that only in particular conditions represent energies. It is ok to give the idea of what they represent but very confusing to declare them as definitions. I think i'll correct in the text soon.  — Preceding unsigned comment added by 151.16.181.249 (talk) 09:29, 19 May 2018 (UTC)
replies: text: Thermodynamic potentials should be thought of as "Thermodynamic potential energies". Energy is force times displacement = dE = F dx. T, P, μ are generalized forces, dS, dV, dN are their respective generalized displacements, and their product is energy. There's also the expression for electrostatic potential energy dE = Vdq. Here the generalized force is the "potential" V in volts and the generalized displacement is charge dq. Unfortunate confusion of terms. PAR (talk) 07:21, 23 December 2019 (UTC)
thread_title:  Definition of thermodinamic potentials 

message: Part of the wiki says "Josiah Willard Gibbs in his papers used the term fundamental functions" but without a citation. Any idea which of his papers he uses that term? Can someone add that citation?  WolfgangECE (talk) 23:44, 21 April 2024 (UTC)
