Ellri, Kessa and I have decided to clone you, from a jellyfish. [quote=Ellri] Not having unsubscribed topic yet, we noticed the statement. Ever fond of facts, we'll give ya some.The only elements not frozen at 59 Kelvin are: Helium, Hydrogen, Neon, Oxygen, Fluorine. They freeze respectively at 1.1K, 14.175K, 24.703K, 50.5K, 53.63K. Oh, and the only gases at 59 Kelvin are: Helium, Hydrogen, Neon. You need at least 90.33 Kelvin to have gaseous Oxygen. [/quote] Ellri, half-pressure also tips the melting/boiling-point some. -Oh, right, reduced pressure LOWERS the melting/boiling points, wiki is decidedly less helpful than Nova/PBS at the quest for absolute-zero*.
