  1. Properties of Water

  2. Polar Molecule • A molecule that has electrically charged areas • Water is polar • Oil is not • Polar and non polar molecules will not mix H+ H+ O-

  3. COHESION • An attraction between substances of the same kind • This is how droplets form • Penny station

  4. ADHESION • An attraction between different substances • examples: • Water on the glass slide, wax paper • Water sticking to you when you get out of the shower • Dew drops on a leaf

  5. Surface Tension • The tension of the surface of a liquid • EXAMPLES: • Water skeeters on a pond

  6. Capillary Action • The tendency of a liquid to move through a narrow tube • Examples • Celery and food coloring • Trees get water to their leaves • Blood flowing through veins

  7. Solution • A mixture in which one or more substance is evenly distributed in another substance • Example: • Kool-Aid I’m a solution. OH, YEAAH!

  8. SUSPENSION • A mixture that contains particles that settle out if left undisturbed • EXAMPLE: • Salad dressing • Dirt • Rivers and streams (Run off)

  9. Universal Solvent • Able to dissolve most substances • EXAMPLE: • Well plate with water and alcohol • Likes dissolves likes • Most things will dissolve in water • Pollution
