      ice, room temperature liquid, and hot vapor — are
      actually only a small part of water’s repertory of
      states,” says Sandia researcher Daniel Dolan. “Compressing
      water customarily heats it. But under extreme compression,
      it is easier for dense water to enter its solid phase [ice]
      than maintain the more energetic liquid phase [water].”</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sandia.gov/news/resources/releases/2007/z-ice.html"><P>In the Z experiment, the volume of water shrank abruptly
      and discontinuously, consistent with the formation of almost
      every known form of ice except the ordinary kind, which
      expands. (One might wonder why this ice shrank instead
      of expanding, given the common experience of frozen water
      expanding to wreck garden hoses left out over winter. The
      answer is that only “ordinary” ice expands
      when water freezes. There are at least 11 other known forms
      of ice occurring at a variety of temperatures and pressures.) </P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/33C1F50B-22A6-462E-8E46-0F2FB95C65DF/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
