Water Info Ppt 12 2009

  1. 1. Properties of Water<br />Accelerated Biology<br />December 2009<br />
  2. 2. Nonpolar Molecules<br />Covalently bonded<br />Electrons equally shared<br />Atoms – similar size<br />
  3. 3. Polar Molecules<br />Covalently bonded<br />Electrons not shared equally<br />Atoms – unequal sizes<br />Charged ends ( + / - )<br />
  4. 4. Hydrogen Bonds<br />Weak attractions between polar molecules.<br />Attraction between + and – ends.<br />Short-term (few trillionths of a sec).<br />Break & reform constantly.<br />
  5. 5.
  6. 6.
  7. 7. A Solution is…<br />2 Substances that combine (solute & solvent)<br />Will a combining 2 substances form a solution?<br /><ul><li>Polar & Polar = solution (Salt & Water)
  8. 8. Nonpolar & Nonpolar = Solution (oil & gasoline)
  9. 9. Polar & Nonpolar = Mixture, not a solution (oil & water)</li></li></ul><li>
  10. 10. Both Polar & Nonpolar substances<br />
  11. 11. Water (attractive forces at work)<br />Cohesion<br />Water sticks (H-bonds) to other water molecules.<br />Adhesion<br />Water sticks (H-bonds) to other molecules or substances other than water.<br />
  12. 12.
  13. 13.
  14. 14.
  15. 15. Surface tension<br />cohesive forces between liquid molecules<br />surface acts as a plastic sheet.<br />
