Water - A Polar Molecule

In this video Paul Andersen explains how the polarity of water makes life on the planet possible.  Oxygen is highly electronegative and pulls the electrons closely creating a partial negative charge.  The polarity of water (and the corresponding hydrogen bonds) create cohesion, adhesion, capillary action, high specific heat, and a universally good solvent.
