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.

[edit] 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 [1]) really mean what's described here. Common Man 23:48, 11 January 2006 (UTC)

[edit] 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)

[edit] Water

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

[edit] 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)
