1. Properties of Water

2. Water is the molecule of life. Water has very unique and important properties. O HH

3. O H H + + _ Water is polar! Negative end Positive end H2OH2O O H H Covalent bonds

4. _ _ _ _ _ + + + + + + + + + + Hydrogen bonds Water molecules are attracted to each other…

5. Hydrogen bonds are responsible for many important properties of water: Water has a relatively high boiling point Ice is less dense than liquid water. Water has a high specific heat Cohesion and Adhesion Water is a universal solvent

6. C Water has a relatively high boiling point

7. Ice is less dense than liquid water.

8. Water has a high specific heat. The water in this pond remains cool even in the summer.

9. Cohesion makes water molecules stick to each other forming beads. Surface tension

10. Adhesion - Water sticks to other things. Water sticks to leave Water climbs up side of test tube

11. Solvent --- water Solute --- sugar Water is a universal solvent
