Transcript of Graphing Data

  • 1. How does this water strider skate on water?

2. The attraction is called aHydrogen bondand the result is that water molecules demonstrate cohesion causing water to have a strong surface called surface tension . 3. Water is aPOLARmolecule:It has a partial negative and partial positive charge. 4. Thehydrogen of one water molecule is attracted to theoxygenof another water molecule like opposite poles of a magnet are! 5. 6. polar= molecule with a partial positive andnegative charge cohesion= water attracted to other watermolecules because of polar properties adhesion= water attracted to other materials surface tension= water is pulled togethercreating the smallest surface area possible VOCABULARY 7. Because water is polar It is called auniversal solvent . A solvent is a fluid that dissolves other substances. The other substance added to the solvent is called the solute.Solvent + Solute = Solution Solute Solvent 8. Because water has bothadhesiveandcohesiveproperties,capillary actionis present. Capillary Actiongives water its adhesive property.Water is attracted to some other material and through cohesion, other water molecules move too as a result of the original adhesion. Ex:Think water in a straw Ex:Water moves through trees this way 9. Green Carnations?
