WATER
Characteristics and Properties
WHAT IS WATER?
Inorganic Compound – derived from nonliving things
Most abundant compound on Earth
Found in nearly every living thing
Water is a Polar Compound
Electrical charge is unevenly distributed
Chemical Formula = H20
Electrical Charge of Water
Hydrogen =
positive chargeOxygen =
negative charge
HYDROGEN BONDING
Hydrogen of one water molecule is attracted to the oxygen of another water molecule.
Partial charges cause water molecules to “stick” together.
This bonding gives water some of it’s unique properties.
COHESION
Ability of water molecules to bond to each other
Surface Tension – cohesion of water molecules at the surface of a body of water.
ADHESION
Ability of water molecules to bond to another surface
Gives water the ability to “stick” to other surfaces.
CAPILLARY ACTION
The ability of water to move through fine pores.
This allows water and any substances dissolved in the water to move through the roots and shoots of plants and blood vessels in our bodies.
CAPILLARY ACTION (2)
Capillary action occurs when adhesion and cohesion work together.
