Here you will find information about matter.

1. What State is Your In?
One property of matter is the state it is in. No, not the state, as in Michigan
or Delaware, but rather the phase of something. For instance, water is normally
in a liquid state or phase, but can also be in a solid state as ice. Water in a gas
state is what we know of as steam or water vapor. Let’s look closer at each
state of matter.
Your toys, your pencil, and your desk
are all examples of solids. The particles
inside of a solid are packed so tightly
together that they never move. That
means, regardless of the shape of the
container, the shape will stay the same.
This is called having a definite shape.
Solids also have a definite space, so their
volume is always constant.
Ice is an
example of a
solid.
Liquids are very different from solids.
Instead of staying together as one solid
shape, it flows and takes on the shape of
whatever container it is in. Therefore, it
has no definite shape. The particles inside
of a liquid are close together, but not
packed tightly like a solid. There is also
definite space, so the volume is also
always the same.
Water, soda, and
coffee are all
examples of
liquids.
Gas is a state of matter where the
particles are really far apart and
constantly bouncing off one another.
These particles are free flowing and
invisible. You could put your hand right
through gas! It doesn’t have a definite
shape, so it just changes based on its
container. Since gas can be compressed,
its volume can actually change. Some
examples of gas is the air you breathe
called oxygen and the air you exhale called
carbon dioxide.
Air, steam, and
helium are all
examples of
gases.

Properties of Solids, Liquids and Gases.
Solids
1. Do not change shape
2. Particles are really close together
3. Particles move very slowly
4. Has fixed volumes
Liquids
1. Takes the shape of their containers
2. There is some space between particles
3. The particles move at a medium speed
sometimes bouncing off each other
4. Has fixed volumes
Gases
1. Hard to contain with no shape
2. Lots of space between particles
3. Particles move very slow rarely bouncing
off of each other
4. Have no volume
