Document Summary
The nature of seawater, the hydrologic cycle, and global climate. Water is often viewed as a typical liquid but it is one of the most atypical liquids known to man. Boiling hot water thrown into the cold air turns into a snowy powder. No other material on earth is commonly found as a solid, liquid and gas. Liquid is the densest at 4 c. Liquid expands when heated (sea level rise) Crazy high heat capacity can absorb a ton of energy. Ocean serves as a huge heat reservoir. High latent heat (why sweating works so well to cool us off) (80-90% of heat absorbed by earth going into oceans) One of the best known solvents on earth. Can dissolve more substances than anything else, even sulfuric acid. 1 electron in orbit around the nucleus. 8 electrons in orbit around the nucleus. Instead of being bonded symmetrically at 180 , the. H atoms are bonded at 105 to the o atom.
