2. States of Water
Matter is found in 3 major states; solid, liquid and gas. Matter that is
composed of atoms packed tightly together are known as solids.
 Solid: Ice
You cannot walk through a solid wall.
The matter is packed so tight that it
prevents you from moving through it.
Solids have a definite shape and volume.
The particles that make up a solid are
closely packed together and do not have
much space to move. Thus, solids keep
their shape. Solid particles are in an
aligned array. Notice the particles are
lined up in tight rows. They are so tight
they can't move, they just wiggle.
 Liquids: Water
Liquids do not hold their shape at room
temperature. There is space between the
atoms of a liquid and they move slightly
all of the time.
Liquids flow or pour and can take on the
shape of a container. If the liquid is
poured into a wider or narrower
container, the liquid will take on that

of milk, the top half of the container would have no milk.
The particles that make up a liquid are farther apart than solids, and
they can move around more readily. This allows liquids to flow and
spread out.
 Gases: Vapor
Gases not only do not hold their shape at
room temperature, they don't even stay
put. Gases are always moving. There is so
much space between the atoms in gas
that you can move around in them easily.
When you walk from one side of the room
to the other, you have walked through a
bunch of gases that make up our air. You
barely even know they are there. Gases
will take on the shape of their container
and can be compressed into a smaller
space. Gas is invisible. That means you
can't see it. The particles are so far apart they are invisible, but they
are still there! Think about oxygen. You can't see it, but you know it's
there because you breath it.
