  • MR BASSET, this is proof that i read it!
    BTW people don't mark this has spam cause that wouldn't be nice.

  • Very nice. Simple, clear and to the point. I'll be able to use this with my special needs biology group. Thank you!!

    Water's Polarity Water's Polarity Presentation Transcript

    • The Properties of Water primarily due to polarity
    • Terms to Know
      • polarity
      • hydrogen bond
      • cohesion
      • adhesion
      • surface tension
      • capillary action
    • Water
      • Most abundant naturally occurring liquid
      • Liquid at most Earth temperatures
      • Unlike most liquids – it expands when frozen
      • The lower density of ice allows it to float (4°C most dense)
    • Water  H 2 O
      • As we know - water is neutral
      • But because the O atom is larger than the H atoms – electrons spend more of their time nearer the oxygen
      • This gives water a slight overall charge
      • That charge is called polarity
    • Polar Bonding
      • Polarity really does allow bonding
      • They are hydrogen bonds and they are very weak
      • They last for fractions of a second
      • Continuously break and reform
      • Polarity really does allow bonding
      • They are hydrogen bonds and they are very weak
      • They last for fractions of a second
      • Continuously break and reform
    • Forces due to polarity
      • Cohesion
      • Adhesion
      • The natural attraction of a water molecule to other water molecules
      • is called cohesion
    • Cohesion
      • Can be seen as water droplets form
      • The attraction of a water molecule to another polar molecule is adhesion
      • Molecules such as soil and clay (dust)
      • Surfaces like glass or paper straws
      • Certain clothing fibers and … animal hair
    • Adhesion
      • Can be seen as water droplets form on the spider web (another polar surface)
      • Two simple properties associated
      • with polarity are
      • Capillary Action
      • Surface Tension
    • Capillary Action
      • We know that gravity is ALWAYS pulling on objects with mass
      • Yet water can move up a paper towel with relative ease - How can this happen?
      • Because the positive and negative charges in the paper attract the polar water molecules ( adhesion )
      • This property of adhesion is called capillary action
    •  
    • Surface Tension
      • Inside a drop of water polar water molecules attract to each other in a random fashion
      • At the surface of the drop, water does not attract to the air
      • A unified layer of molecules at the surface creates surface tension
      • There the water behaves like an flexible sheet allowing denser objects to “sit” on the surface
    • Surface Tension
