  • 4. 2 HYDROGEN ATOMS Water Molecules What do you observe? ALL HELD TOGETHER BY COVALENT BONDS ONE OXYGEN ATOM
  • 5. Water has several special properties that make it so important to all living things
  • 6. Water is a Polar Molecule The poles, or ends of the molecule, have weak opposing charges.
  • 7. Water’s Polar Nature Causes Cohesion & Adhesion Cohesion - Similar forces attracted Adhesion - Opposite forces attracted
  • 8. It also makes it a great solvent Actually, it is the “universal solvent”
  • 9. Water has surface tension Hydrogen bonding and cohesive forces cause water molecules to “stick” to each other
  • 10. How does water get from the roots of tall trees like redwoods to the very top leaves?
  • 11. Capillary Action The ability of water to move against the force of gravity, using the properties of adhesion and cohesion
  • 12. WHAT DOES THESE TWO IMAGES HAVE TO DO WITH THE PROPERTIES OF WATER?
  • 13. Water also has a high specific heat capacity This means it takes a lot of energy to heat it, or to cool it off This energy is actually necessary to break the hydrogen bonds
  • 14. How does this relate to your body in terms of temperature?
