Water, Water Everywhere

I. Water is Polar
• Water is slightly charged on either end.
II. Water is a Universal Solvent
• Solvent – Substance
that does the dissolving.
• Solute – Substance that
gets dissolved.
• More things dissolve in
water than anything
else. This is important
because many chemical
reactions only occur
when the reactants are
dissolved.
III. Water has a high specific heat
• It takes a lot of energy to raise 1 gram of water
by 1˚C. This means water heats up and cools
down slowly.
IV. Water is less dense as a solid
• Water expands when it freezes. This is why ice
floats.
V. Water is Cohesive
• Water sticks to itself.
Cohesion is important to….
• Water Striders!
• This creates surface tension, allowing water
striders to “walk on water”.

VI. Water is Adhesive
• Water sticks to other objects.
• Capillary action is when water sticks to small
tubes and climbs up against the force of
gravity.
Adhesion is important to…
• Plants! This is how they
get water from their
roots to their leaves.
