1. Water Notes

2. Water is a polar molecule.
A water molecule is Polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
The hydrogen end is positive and the hydrogen end is negative.

3. Cohesion- water molecules are attracted to other water molecules.
This creates Surface Tension- this means water is able to resist rupturing when under pressure; creates a “film” on top of the water.

4. Hydrogen Bonds
Water molecules adhere to each other using WEAK hydrogen bonds.

5. Adhesion- water molecules are attracted to different molecules

6. Adhesion and Cohesion Together create Capillary Action
Capillary Action allows water to move against gravity from the roots of a plant to the leaves or flowers.

7. Water = Universal Solvent, dissolves ALMOST anything (Not lipids)
Solutions are composed mostly of water ex) Salt Water
Solute – The substance being dissolved. Ex) salt
Solvent – The substance in which the solute dissolves. Ex) water
