frozen
sciencepunk | June 28, 2011Following on from last week's discovery of water that can freeze at room temperature, here's another trick. Water at minus 130 degrees Celsius can flow like a thick fluid. The work carried out by Ove Andersson, a physicist at Umeå University, showed that by increasing pressure to 10,000 times the norm, ice could be coaxed into a viscous liquid state 30% denser than normal water. The findings lend support to the theory that water has two liquid phases, one at much higher density than the other. I'd imagine it also means liquid water is likely to exist even on frozen planets.
