Class water

1. Water

You will:
- explain the properties of water and its importance for living organisms

2. Properties of water

• Universal solvent
• Surface tension
• Cohesion
• Adhesion
• High heat capacity
• Low density at solid state

3. Universal solvent

• Water is a common solvent for most biochemical reactions.
For example water dissolves sugar

4. Surface tension

• Surface of water allows to resist to external force

5. Cohesion

• sticking of water molecules to each other

6. Adhesion

• sticking of water molecules to another (not water)
molecules

7.

8. Heat capacity

• high heat capacity water regulates body temperature.

9. Low density at solid state

• low density at solid state making ice float, it helps aquatic organisms
to survive at subzero (below 0) temperatures in winter
