1. Properties of Water

2. What makes water so special?1

3. Properties of Water Polar Cohesion Surface Tension Adhesion
Capillary Action
High Specific Heat
Less Dense as a Solid
Universal Solvent 1

4. Water is Polar Oxygen has a partial (-) charge
Hydrogen has a partial (+) charge
Causes water to be POLAR, like a magnet

5. Covalent Bond vs. Hydrogen Bond
VIDEO

6. Cohesion
Water molecules attracted to each other creating surface tension 1

7. Surface Tension
The tightness across the surface of water caused by cohesion
Makes the surface act like a solid 1

8. Adhesion
Water molecules are attracted to other substances such as glass, soil, and plant tissues 1

9. Capillary Action VIDEO Ability of water to “climb” up against gravity
Results from Cohesion + Adhesion
EX: Water moving up the roots to the top of the tree

10. High Specific Heat
Amount of heat (energy) required to raise the temperature of water by 1⁰ C VIDEO
WATER = 75°F
BEACH = 200°F 1

11. Water is Less Dense as a Solid
Water in a liquid state keeps rebonding and changing its shape
Water in a solid states has a fixed shape with space in between making it less dense

12. Universal Solvent
Water is a universal solvent because it dissolves more substances than any other liquid 1
