Supercool, And Strange - Scientists Are Finding Clues About Why Water Is So
Utterly Weird, Science News
 









Excerpts:     MULTIPLE PERSONALITIES. Water's many forms, or phases, change with
shifts in temperature and pressure. Below -38 degC, at high enough pressures (a
region researchers call "no man's land"), water may remain liquid. The precise
locations of the phase boundaries are uncertain, but those shown here are
supported by computer simulations. E. Roell/S. Norcross     You wouldn't expect
to learn much about the properties of water by watching a square dance. But
think again. Following the caller's lead, the dancers meet, separate, weave, and
swing in a perfectly fluid manner.  It turns out that similar coordinated
maneuvers - with water molecules taking the places of the dancers - may be
responsible for some of water's most puzzling features, an array of recent
research findings suggest.
