Water has
several special
properties that
make it so
important to
all living
things
Water is a
 Polar
 Molecule
  The poles, or ends of the
molecule, have weak
opposing charges.
Water’s Polar Nature Causes
Cohesion & Adhesion

   Cohesion - Similar forces
attracted



   Adhesion - Opposite
forces a...
It also
makes it a
great solvent
Actually, it is the “universal
solvent”
Water has
surface
tension
   Hydrogen bonding and
cohesive forces cause water
molecules to “stick” to each
other
How does
water get from
the roots of
tall trees like
redwoods to
the very top
leaves?
Capillary
Action


The ability of water to move
against the force of gravity,
using the properties of
adhesion and cohesion
WHAT DOES THESE TWO IMAGES HAVE TO
 DO WITH THE PROPERTIES OF WATER?
Water also
has a high
specific heat
capacity
    This means it takes a lot of energy to heat
it, or to cool it off

How does
this relate to
your body in
terms of
temperature?
