Talk:Clausius-Clapeyron relation

Thanks for creating this article

I created two redirects to this article: Clausius-Clapeyron equation and Clausius-Clapeyron relation. Both redirects use the ordinary dash ( - ) on our keyboards. The difference between that and the dash that I think you used is ( - – ). Most readers will probably use the keyboard dash to search for this article. Anyhow, thanks for creating this article.

Suggested revision of lead-in sentence

Paul, to me, a single-component is a single pure compound like say butane and liquids like gasoline or an aqueous solution of ethanol (which are mixtures of compounds) are not single-component systems. In the lead-in sentence, should it be revised to say "...an equation for a system consisting of two phases of matter in ..." rather than the current "...for a single-component system consisting of two phases in ..." ?

Milt, I must confess that I don't have any hands-on experience with the C-C relation. But reading about it, I got the impression that it applies to single (pure) components only. At least the derivation is for pure systems, because it deals with only one chemical potential μ. It seems to me that for mixtures the proof must be extended with more μ's. Do you know anything about that?--Paul Wormer 16:16, 12 September 2009 (UTC)
