Objectives
• Know the chemical composition
of water.
• Recall the distribution of the
water here on earth. This will
include bodies of water.
• Understand how the properties
of water affect how the
environment functions.
• Application of the properties of
water in our daily activities.
Composition
of Water
• 2 Hydrogen atoms
• 1 Oxygen atom
Distribution of
water
Roughly 70% water
• 97% saltwater
• 2% polar ice caps
• 1% freshwater
Properties of
Water
1. Density
Mass per unit volume.
• water: 1 g/ml
• Seawater: 1.03 g/ml
• Ice: 0.92 g/ml
2. Surface
Tension
Ability of a liquid to shrink
to the smallest possible
surface space.
3. Cohesion
Attraction of molecules of
the same kind.
4. Adhesion
Attraction of molecules of
different kinds
5. Capillary
Action
Ability to move through
tight spaces

6. Heat Capacity
Amount of heat needed to
raise 1 gram of matter by 1
degree Celsius.
6. Heat Capacity
Water boils at 100 degree
Celsius or 212 degrees
Fahrenheit at 1 atm
Freezing point: 0 degree
Celsius or 32 degrees
Fahrenheit
7. Universal Solvent
Water can dissolve almost all
substances
Solvent – the chemical in which
substances dissolve in
Solute – the chemical that dissolves
in the solvent
