Directions: HIGHLIGHT answers to the questions in the reading before answering the questions.
The three most familiar states of
matter are solid, liquid and gas. Each
of theses states of matter is called a
phase. Particles of matter in each
phase are arranged differently and
have different ranges of motion.

The shape and volume of a rock are the same
whether you put the rock in a shoe box or on a
rock pile. When matter has a definite shape and
a definite volume, it is a solid. A solid has these
characteristics because its particles are closely
packed. The particles can move slightly but they
do not change positions.

Matter with a definite volume, but no definite
shape, is a liquid. Particles in a liquid behave
sometimes like bird seed in a sack. Like the
bird seed, the liquid particles easily slide over
each other. As a result, a liquid will take the
shape of its container.

The particles in a liquid are close together, but
move enough so they do not stay in fixed positions.
The particles flow freely past one another.
Some liquids, like water,
flow quickly because there
molecules are further
apart. Other liquids, such
as honey, corn syrup,
molasses, or motor oil,
flow more slowly because
the particles tend to be
closer together.

Matter that has no definite shape and no
definite volume is a gas. Like a liquid, a
gas will take the shape of any container.
Unlike a liquid, a gas expands to fill
whatever space is available. In other
words, the if the container gets larger,
the gas molecules will spread out more to
fill the space. The scent of a flower and
the odor of a rotten egg come from
gases that can fill a room.
