1. Physical and Chemical Changes and Properties
Read through these notes to help you fill out your graphic organizer! You must include DEFINITION, at least 2 EXAMPLES, and at least 1 PICTURE
(no picture needed for intensive vs. extensive properties)

2. Classifying Properties
Properties can be grouped into 2 general types: physical properties and chemical properties.
Properties can be defined as characteristics that a substance exhibits.
They can be used to describe and classify matter.

3. Physical Properties
Can be observed or measured without changing the identity of the substance.
Commonly used to describe a substance
Ex: Boiling Point

4. Chemical Properties
A chemical property relates to a substance’s ability to undergo changes that transform it into different substances.
This can only be observed through experimentation.
Ex: Ability to Rust

5. Intensive vs. Extensive Physical Properties
All properties can help reveal the identify of an unknown substance; however conclusions usually can not be made based on only one property
Properties can be further classified as either intensive or extensive

6. Extensive Physical Properties
Will change depending on the amount of matter that is present.
Ex: Volume

7. Intensive Physical Properties
Will stay the same regardless of the amount of matter present.
Ex: Color

8. Physical Changes
No new substance is created; matter only takes on a new form/appearance
Can be changed back
Ex: State Changes – Solid to Liquid

9. Chemical Changes
A change in which one or more substances are converted into different substances
Irreversible – can not be changed back
Ex: Paper Burning (combustion)

10. Chemical Changes Indicators of a Chemical Change Color change
Formation of a gas
Temperature change
Formation of a precipitate
Emission of light
Combustion (fire/cooking/baking)
