What does this sentence mean? — Preceding unsigned comment added by 217.156.156.69 ( talk) 13:36, 12 May 2017 (UTC)
I agree, that sentence doesn't make sense. -- 131.111.185.34 ( talk) 10:53, 16 November 2017 (UTC)
I think it would be useful to relate free energy to the concept of partition function.. Also, to show how occupation numbers/density as well as magnetization/etc are related to it. It would be cool if someone writes this, if now, I guess I can write it when I have more time. IlyaV ( talk) 02:46, 13 May 2010 (UTC)
It's very misleading to say that chemists use one free energy and physicists use the other. Helmholtz free energy is a very important notion for explosives chemistry, because naturally, PV is not really a going to be a controllable term.
Why is Merle Randall referenced? At the very least, a description should be added to who he was. Also seems like if you are to include him, Helmholtz, Gibbs and Lewis ought to be linked as well. Thermodude 15:56, 10 July 2007 (UTC)
The current "overview" section is really a commentary on things given for granted as if they were already acquired. I suggest that someone could write a real overview section to this page, which should ideally be understandable to a middle school student. People who can readily understand this page, as it currently is, are likely to be already knowledgeable in the field, and certainly have access to more in-depth coverage from thermodynamics textbooks. The remaining people may not be able to follow the explanation without jumping from one "prerequisite" definition to another. This makes this, and similarly conceived pages, practically useless. Most subjects can be explained to a 12-year old, as Einstein suggested, if your aim is just to illustrate things, not to train experts; and if they turn out to be too complicated, then it is most often the teacher's, not the student's fault. —Preceding unsigned comment added by 130.251.61.251 ( talk) 08:12, 27 January 2010 (UTC)
"The free energy is the internal energy of a system less the amount of energy that is not unusable to perform work, given by the entropy of a system multiplied by a reference temperature." - could someone reformulate this sentence? I don't get it. gretts —Preceding unsigned comment added by 130.133.8.114 ( talk) 10:31, 2 December 2010 (UTC)
Energy is a generalization of free energy.
