Water
Water is used all around us everyday and is essential in
the maintenance of life
...

Substituting other fluids for water can negatively impact
one's health, especially in the case of children
...
For teens and adults,
reliance on fluids other than water also has side effects
...

Water is an odorless, tasteless, and transparent liquid
...
Water is the most
common liquid on earth
...

Water is made up of two atoms of hydrogen and one atom
of oxygen
...
The two H-O bonds form
an angle of about 105 degrees
...
A polar molecule is a molecule with a

net positive charge at the hydrogen ends and a net
negative charge toward the oxygen end
...

Surface tension is a result of the water molecules clinging
tightly together
...
The only liquid
with a greater surface tension than water is mercury
...
Therefore, mercury's
surface is able to hold heavier objects up, unlike any other
liquid
...
Water has a high heat of vaporization
...
Hydrogen bonding also plays a role
in water's high heat of vaporization
...
These molecules break
loose from the surface and enter the air
...
Therefore, the hotter
the liquid gets, the more vaporization occurs
...
This process requires taking heat from
its surroundings, which, in turn, cools those surrounding

elements
...

Freezing of water occurs when its density increases
...
The
molecules start to move slower and the space decreases
between them
...
Water in
solid form takes up a greater amount of volume than water
as a liquid
...

Water supports many different processes
...
Water is
the most abundant liquid on earth and is also the most
important
