2. Atoms, molecules and Energy Break=release Add=store

3. Why Water? High heat capacity Absorbs and releases large Amounts of HEAT before Changing temps (that’s why when it’s 100 0 Outside…you’re not)

4. Beach water in April-May Beach water in Oct-Nov

5. What’s up with Fog?

6. High Heat of Vaporization Takes large amounts of heat energy to break hydrogen bonds holding water together

7. Where does sweat get energy to vaporize?

9. Polar/Solvent Properties Universal solvent ALL chemical reactions require water MAIN transport system for nutrients, gases and wastes

10. Everything is carried in solution food, gases, hormones, vitamins, minerals
