1. CHAPTER 3 PROPERTIES AND CHANGES OF MATTER
SEC 1
PHYSICAL & CHEMICAL PROPERTIES

2. What you’ll learn? IDENTIFY PHYSICAL AND CHEMICAL PROPERTIES
CLASSIFY OBJECTS BASED ON PHYSICAL PROPERTIES

3. Why it’s important?
Understanding the different properties of matter will help you to better describe the world around you.

4. New Vocabulary:
Physical Property
Chemical Property

5. All substances have properties… Including people
Example: People can be identified by their …

6. What are properties? Matter has observable and measurable qualities.
We can use general properties to identify substances.
Two basic types of properties of matter: Physical properties and Chemical properties…

7. Physical Properties
Physical properties are used to identify, describe and classify matter.
Characteristic of a substance that can be observed (using your senses) without changing the substance into something else.

8. More EXAMPLES - Physical
size, shape, freezing point, boiling point, melting point, magnetism, viscosity, density, solubility, luster and many more.
Density- amount of mass in a volume
Solubility- number of grams of one substance that will dissolve in 100g of another substance at a given temp.

9. PHYSICAL PROPERTIES Dependent on size Mass, weight, volume
Independent of size
Density, melting, boiling, solubility, magnetic, state and color

10. Chemical Properties
A characteristic that cannot be observed without altering/changing the substance.
