Properties of water

  1. 1. The Properties of Water By: Leigh Aaron Biology 4 th hour
  2. 2. Adhesion <ul><li>The attractive force between molecules in one phase and different molecules in another phase. </li></ul> Drops of water forming a dome on top of a penny is an example of adhesion.
  3. 3. Cohesion <ul><li>The attractive force between similar molecules in the same phase. </li></ul>
  4. 4. Hydrogen Bond <ul><li>A weak to moderate attractive force between a hydrogen atom bonded to oxygen, nitrogen, or fluorine, and an oxygen, nitrogen, or fluorine atom on another molecule. </li></ul>
  5. 5. Hydrophilic <ul><li>Water loving; a hydrophilic substance readily dissolves water. </li></ul>Sugar/glucose is a hydrophilic substance.
  6. 6. Hydrophobic <ul><li>Water-fearing; a hydrophobic substance does not dissolve in water </li></ul>Examples are: oil, wax, etc.
  7. 7. Polar Covalent Bond <ul><li>A covalent bond in which the electrons are not shared equally , giving the bond some ionic character. </li></ul>
  8. 8. Solvent <ul><li>A liquid which dissolves another substance without any change in its chemical composition (such as water). </li></ul>
  9. 9. Specific Heat <ul><li>The amount of heat needed to raise the temperature of a 1 gram sample of a substance by 1 degree Celsius. </li></ul>
  10. 10. Surface Tension <ul><li>The energy needed to increase the surface area of a liquid by a given amount. </li></ul>
