Talk:Critical temperature

Personally, I would recommend moving this link back to "Critical Properties", since it refers to both critical temperature and critical pressure. --[[user:stokerm|Matt Stoker

Can anyone explain me why we have, for hydrogen and helium :

Tc = Tc + 8K

Pc = Pc + 8atm?

I know it's known as Newton's correction, but i can't find any reference to this on the web. -ClapBedon

Superconducting critical temperature
Can this be covered here or on a different page? I don't think the references we have so far (see also ) really mean what's described here. Common Man 23:48, 11 January 2006 (UTC)

Revised with references
The original table was unreferenced. I gave references for the new table, adding critical pressures and dropping some elements not in the references. Critical Pressure redirects to this page, so the expansion of the table and the highlighting of that phrase is appropriate. --Ben Best 21:23, 3 December 2006 (UTC)

Water
Water can be solidified too, at sufficiently high pressure. That "other than water" in the beginning is unnecessary.

Error in precision
The critical temperature of tungsten is listed as 15500 K, and beside it, the Celsius temperature is supposed to be 15227. Since reliable measurement of such high temperatures is not currently possible, it seems obvious to me that the figure of 15500 K was calculated using thermodynamic methods, and that the two zeroes are not significant digits. But then, when one subtracts 273 to convert to Celsius, the answer should be 15200, due to a lack of significant digits further to the right. I have seen errors like this everywhere, even in the Guinness World Records. Who agrees with me? Bbi5291 (talk) 20:05, 8 April 2008 (UTC)

merge to critical point
This article does not appear to be sufficiently distinct to be its own. Should it be merged? Potatoswatter (talk) 16:25, 19 May 2008 (UTC)
 * This tag was added at one but not both pages. Suggest a bit of time to evaluate starting june 11-08 --Kevin Murray (talk) 20:24, 11 June 2008 (UTC)


 * Merge from critical point (thermodynamics). This article is more intricately stated and referenced than that one, and critical point has meaning in mathematics that is useful in comprehension. For that matter, points hav an imajinary definition. BrewJay (talk) 23:35, 24 July 2008 (UTC)

As a professional Chemist, I've always heard it's "Critical Point". "Critical Temperature" is something else entirely (in chemistry-speak, it's the temperature at which a compound decomposes), and merging the definitions is not just confusing, it's incorrect. 67.160.227.30 (talk) 06:08, 3 September 2008 (UTC)


 * If you think the material here belongs in critical point, then you support the merge proposal. Potatoswatter (talk) 07:29, 3 September 2008 (UTC)
