This document discusses the three states of matter - solids, liquids, and gases. It defines each state and explains how their particle arrangements differ. Solids have a definite shape and volume, while liquids have a definite volume but not shape, and gases fill their container. The document also covers physical changes like melting, freezing, and evaporation which alter a substance's state without changing its chemical makeup. Finally, it defines mixtures as combinations of materials that retain their individual properties, and solutions as mixtures where one material disseminates evenly throughout another.

Is matter that has a definite size
and shape.
Definite= it stays the same.
If you put it in a jar or a box, it
stays the same.

will take on the shape of glass.

Is matter that has no definite
shape or volume.
Gas takes the shape of whatever
container they are in.
The air all around us is a gas.

6. Ch.11, Lesson 2
(comparing solids,
Liquids and Gases)
Matter is made of particles.
Particles are very, very small.
In Solids particles are packed
closely together, so they form a
certain pattern.
In Liquids particles are close
together but don’t form a pattern.
They have more energy and can
slide past one another.
In Gas particles have more
energy, they spread out to fill a
large container, or squeeze
together to fit into a small one.

How can Matter change?
Matter can change but still remain
the same kind of matter.
* If you cut a paper, it will look
different but still made of the
same particles.
* If you cut and sand the wood to
make a wooden model, its shape
and size change but it is still
wood.

looks, but not in the kind of
matter it is.

Matter can also change in
state.
We can find water in the
solid, liquid, or gas state.
Water looks different in
each state but it is still the
same kind of matter.

(comparing solids,

Ice is the solid state…..particles
are close together, they don’t
move very much.
When ice is heated …..it melts, so
change from solid to liquid
state…..particles have more
energy and move faster.
When water is heated….it
evaporates, change from liquid to
gas state and called water vapor.

(comparing solids,

When water vapor cools….it looses
energy and condenses…..it
becomes liquid.
When liquid water cools, it
freezes into ice.
Melting, evaporating, condensing,
and freezing are examples of
physical changes.

Can you mix different kinds of
matter together?
When you mix different kinds of
matter together.
In a mixture the properties of
each kind of matter don’t change.
Ex. Fruit salad is a mixture of
many kinds of fruit, if you pick out
a piece of orange it will look like
any orange piece.

What is a solution?
 Is a kind of mixture.
 It forms when one or more
kinds of matter are mixed
evenly in another kind of
matter.
 It is a physical change.
 Ex. Salt water, if you mix salt
with water….you can’t see the
salt anymore.
