Water: A Polar Molecule
Why water is a polar molecule. He also explains why this gives water properties like cohesion, high specific heat, less dense ice, and the ability to act as a solvent. All of these properties are due to hydrogen bonding.
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.
