Why Water? High heat capacity Absorbs and releases large Amounts of HEAT before Changing temps (that’s why when it’s Outside…you’re not)
Beach water in April-May Beach water in Oct-Nov
What’s 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
