The water molecule, shaped like a wide V, is a polar molecule, meaning that opposite ends of the molecule have opposite charges. ~ Hydrogen bonds result in adhesion and cohesion, ability to stabilize temperature, expansion upon freezing, and versatility as a solvent. * Regulation ~ Water stabilizes air temperatures by absorbing heat from air that is warmer and releasing the stored hear of air that is cooler. ~ pH level regulates chemical processes ~ Buffers allow biological fluids to resist changes to their own pH when acids or bases are introduced....
