Liquid helium..can it be used to cyogynic a carnation back to like?


[edit] From PNA/Physics

  • Liquid helium Could use a lot of info, such as uses of liquid helium and some technical informations and charts.
Should be merged with Helium and Superfluid, I think. Zaha 15:57, 27 Sep 2004 (UTC)
I've taken a stab at rewriting and expanding this article. It would be nice if phase diagrams could be included. The article could be merged with Helium, but liquid helium is not always superfluid, especially in its commercial applications; so it would not be appropriate to merge it with Superfluid. M. S. Pettersen, 29 Sep 2004.

I removed this sentence: "Solid helium requires a temperature of 1–1.5 K and about 26 standard atmospheres (2.6 MPa) of pressure [ref: Natures Building Blocks, page 178]" Helium cam solidify at temperatures outside this range, so temperatures of 1-1.5 K are not required; and the pressure required depends on whether you're talking about helium-3 or helium-4. The correct information about the melting pressure is given in the table (see the cited reference by Wilks). (Wilks' book is a professional monograph, while Nature's Building Blocks is a popularizing work, which is either wrong, or misquoted here). 67.186.28.212 15:14, 18 August 2006 (UTC)
