Everyone gets to be an atom… Link your arms and make a water molecule
How do water molecules behave when they are around each other?
What does the polarity of H2O mean for the behavior of water? • Cohesion/Surface tension • Solubility
Cohesion/Surface tension • Cohesion is… • Surface tension is…
Solubility • Like dissolves like • Polar compounds dissolve other polar compounds and ionic solids (Water dissolves NaCl)
Solubility • Nonpolar compounds dissolve other nonpolar compounds (Fats and oils dissolve each other)
Recap: polarity of water… • Cohesion/surface tension • Solubility Next… • Phase changes • Specific heat
