4. T.1 Properties of Matter What is matter?
What are three states of matter?
What is the difference between physical and chemical properties?
What is the difference between physical and chemical changes?

5. Properties of Matter
What is matter?
What are examples of matter?

6. Extensive vs. Intensive Properties
Extensive - property that depends on the amount of matter in a sample
Examples: mass, volume
Intensive - property that depends on the type of matter in a sample, not the amount of matter
Examples: color, odor, boiling point

7. Properties of Matter
Read pages 73 an 74 to distinguish between physical and chemical properties. State 2 examples of each property.

8. Physical or Chemical Property?
Color
Flammability
Density
Boiling point
Reactivity
Toxicity
Flexibility

9. Copy this chart into your notes
Solid
Liquid
Gas
Definite
Shape?
Volume?
Easily compressed?

10. States of Matter

11. Physical vs Chemical Changes
Using pages 76 & 77 in your text book, define physical change & chemical change

12. Physical or Chemical Change?
Sugar dissolving in warm water
A nail rusting
Glass breaking
Paper burning
Iron and sulfur are heated to form a gray substance
Water boils at 373K
Vinegar reacts with baking soda

13. Reversible vs Irreversible Physical Changes.
What do you think is the difference between the two types of physical changes?
Are the following reversible or irreversible?
- Ice melting
- Cracking an egg

14. Review Make a Venn Diagram comparing liquids and solids
Make a Venn Diagram comparing liquids and gases
Make a Venn Diagram comparing solids and gases
You have 4 samples, all of various sizes, of pure aluminum. Do all samples have the same extensive and intensive properties? Explain your answer.
Look back at the Chemystery. Identify the physical and chemical changes. Are the physical changes reversible or irreversible?

20. Compounds
– A substance that contains two or more elements chemically combined

21. Mixtures - Blends of two or more pure substances - Two types:
1. Heterogeneous - mixture with visibly different parts
2. Homogeneous - mixtures that do not contain visibly different parts. Also called solutions!

22. Checkpoint
At the beach, you realize that both ocean water and sand are mixtures. Which is a homogeneous mixture (or solution)? Which is a heterogeneous mixture?

23. Separating Mixtures Distillation Filtration
separates a solid from a liquid in a heterogeneous mixture
liquid is boiled to produce a vapor that is then condensed into a liquid
