Learning Targets Ch 2 Chemistry and Water Atoms, molecules and Energy Break=release Add=store Why Water? High heat capacity Absorbs and releases large Amounts of HEAT before Changing temps (thats why when its Outsideyoure not) Beach water in April-May Beach water in Oct-Nov Whats up with Fog? High Heat of Vaporization Takes large amounts of heat energy to break hydrogen bonds holding water together Where does sweat get energy to vaporize? Polar/Solvent Properties Universal solvent ALL chemical reactions require water MAIN transport system for nutrients, gases and wastes Everything is carried in solution food, gases, hormones, vitamins, minerals Building and Breaking Need Water Ana +Cat = Meta
