1. Chapter 3: Matter—Properties and Changes
Tammilee Kerr

2. Section 1 Properties of Matter

3. Substances Matter: is anything that has mass and takes up space.
Matter is everything around us
Examples: Rock, water, air, cup
Pure Substance: Matter that does not change its composition
Examples: Pure Water
Example: Tap Water and sewage are not pure substances

4. States of Matter 4 states of matter: Solid, Liquid, Gas
Solid: Definite volume and definite shape
May not take the shape of a container
Volume does not change

5. States of Matter 4 states of matter Cont’d
Liquid: Flows but has definite volume and indefinite shape
Particles move past each other so shape can change
Volume does not change

6. 4 states of matter Cont’d: Gas: Indefinite volume and indefinite shape
Takes the shape of a container
Volume Changes

7. Properties and Change
Physical Properties: A characteristics of matter that can be observed or measured without changing the properties composition
Chemical Properties: The ability of a substance to combine with or change into one or more other substances is called a chemical property

8. Properties and Change
Physical Properties: A characteristics of matter that can be observed or measured without changing the properties composition
Extensive Properties: Dependent on the amount of substance (matter) that is present
Example
Mass
Length
Volume
Intensive Properties: Do not depend on the amount of matter that is present.
Melting point
Boiling point
Ability to conduct electricity
Ability to transfer heat

9. Properties and Change
Chemical Properties: The ability of a substance to combine with or change into one or more other substances is called a chemical property
Terms associated with a chemical change
Decomposition
Rust
Color Change
Change in temperature
Change in smell
Production of a gas
Example: Iron + O2  Rust
Example: Copper + O2  Color Change
