  1. Polarity of water

  2. Everyone gets to be an atom… Link your arms and make a water molecule

  3. Why does water have split partial charges?

  4. How do water molecules behave when they are around each other?

  5. Water in different states of matter

  6. What does the polarity of H2O mean for the behavior of water? • Cohesion/Surface tension • Solubility

  7. Cohesion/Surface tension • Cohesion is… • Surface tension is…

  8. What does it mean to dissolve?

  9. Solubility • Like dissolves like • Polar compounds dissolve other polar compounds and ionic solids (Water dissolves NaCl)

  10. Solubility • Nonpolar compounds dissolve other nonpolar compounds (Fats and oils dissolve each other)

  11. Recap: polarity of water… • Cohesion/surface tension • Solubility Next… • Phase changes • Specific heat
