Water properties.
<P>
   A  water  molecule  is  held  together by strong, polar covalent bonds
   between oxygen and hydrogen atoms.
<P>
   The  partially charged regions of a polar water molecule are attracted
   to oppositely charged parts of neighboring molecules.
<P>
   Each  molecule  can  form  weak  hydrogen  bonds to multiple partners,
   conferring water unique properties.
<P>
<BR><LI> Cohesion and surface tension.
<BR><LI> High specific heat.
<BR><LI> Expansion upon freezing.
<BR><LI> Versatile solvent for hydrophilic substances.
