17. 3 States of Matter
Matter: has mass and occupies space; "an
atom is the smallest indivisible unit of
matter"

18. GAS
A form of matter that does not have a definite
volume or shape. Particles separate from each other
and spread out.

19. LIQUID
A form of matter that flows, has constant volume, and
takes the shape of its container. Composed of
molecules that move freely among themselves but do
not tend to separate like those of gases.

23. Matter
Properties of
Everything--the human body, hamsters, ketchup, spoons, soda--is made of matter. Matter
has physical or chemical properties.
Physical properties are the traits of an object you can see such as
size, color and state. Changing these properties does not change the chemical nature of the
matter. For example, a paper that is cut into small pieces has undergone a physical change.
The pieces have a different quantity, size, shape and texture than the original sheet.
Chemical properties are the characteristics that describe the
composition of matter. When metal combines with oxygen, it makes rust
(oxidation) and changes the chemistry of the metal .
Physical and chemical traits are constantly changing
in reaction to the environment. Bread gets moldy.
Sneakers wear out. Statues rust. The changes that
occur are called either physical or chemical changes,
depending on the trait that is being altered.
.

24. Physical changes are usually easy to identify because you
can see the change. When ice melts, you can see water
pooling in its place. When a crayon is used to draw, the crayon
breaks into millions of tiny pieces. The color of the crayon, in
your hand and on the drawing, is the same; only the size and
shape of the matter has changed.

25. Chemical changes occur at the atomic level, we can't
actually see them happening. There are three main signs to
look out for when trying to identify a chemical change.
•the appearance of a new substance,
•irreversible change has occurred
•the absorption or release of energy.
Different types of chemical changes have names that
describe the processes occurring. (decomposition,
photosynthesis, oxidation (rusting), ripening, cooking)

26. Practice: Is it a physical change or chemical change?
A paper burned.
The firework exploded.
The leaves turned color in Autumn.
Sugar dissolves in a cup of water.
The bicycle has rusted.
The apple has spoiled.
I crumpled the newspaper.
The glass vase shattered
And can’t be fixed.

27. Think About It...
Identify four physical changes that occur in your kitchen.
Need some help? Here are some examples of physical
changes.
Bread crumples.
Boiling water evaporates.
The paper towels roll is built to undergo physical change-perforations make it easy to rip into smaller pieces.
A sponge can expand when it soaks up water, or shrink as it
dries.

28. Think of 2 chemical changes that can occur.
Here are some examples.
•Bread molding--Mold, a living organism, is consuming the sugar, water
and minerals in the bread. And the bread is decomposing. These
changes are irreversible, release smelly gases and produce a small
amount of heat.
•Cake baking--When you bake a cake you are combining several
ingredients into a solution, adding energy (heat) and making a new
material that cannot be returned into the original ingredients.
