Property.
Measuring Matter
What are States of Matter?
Solids:Is matter with a volume and
shape that stay the same.
Liquids: Is matter that has a volume
that stays the same but a shape that can change.
A liquid takes the shape of whatever container holds it.

A gas has no definite shape or volume.
A gas takes up all the space in a container.
Changes of State
Evaporation Condensation
The change of liquid to a gas.

How does the matter changes?
Physical ChangesChanges in matter that don’t form new kinds of matter are physical changes.
Physical Changes

Example #2
Knitting
Physical Changes
Knitting a wool cap. The thick wool is cut from sheep in spring.
The wool is combed into soft strands, which are pulled into threads and twisted to make yarn.A knitter then knits the wool yarn into a cap.
In the cap, the wool looks different from the way it looked on the sheep, but it is still wool.

Example # 3: MixtureA mixture is a substance that is made up of two or more kinds of matter.
You put different types of matter together, but no new types of matter are formed.
Solution
