1. What is matter?
Anything that takes up space and has volume

2. States of Matter Solid Liquid Gas Plasma
High temperature physical state of matter in which atoms lose their electrons
Stars
Electronic Devices
Aircraft and Automobile engine parts

3. Physical vs Chemical Talking about matter . . .
We can analyze matter by looking at two categories:
Physical vs Chemical

4. Talking about matter . . .
Physical

5. Property vs Change Physical
A characteristic that can be observed or measured without changing the identity of the substance
A characteristic that can be observed or measured when one substance changes into another state (solid, liquid or gas) but does not change its identity

6. Property vs Change Physical
A characteristic that can be observed or measured without changing the identity of the substance
Examples:
Odor
Shape
Density
Size
Melting point
Boiling point
Color
A characteristic that can be observed or measured when one substance changes into another state (solid, liquid or gas), but does not change its identity
Examples:
Cutting evaporating
Melting condensation
Boiling subliming
Splitting deposition
Cracking grinding
Crushing breaking

7. Practice – Physical Property or Physical Change
Rubbing alcohol evaporating
Paper being cut in half
The density of water is 1.00 g/mL
Breaking a glass window with a baseball
Diethyl ether has a boiling point of 34 °C
Sucrose has a malt-like odor
Dry ice subliming
Gold has a melting point of 1,064 °C
Sawing a piece of a fallen tree branch in half

8. Key Vocab. for Physical Observations
Malleable – hammered or beaten into thin sheets
Ductile – easily drawn into a wire
Luster – metallic or shiny appearance
Brittle – breaks easily, shatters

9. Compare and Contrast these 2 chemicals

10. Observations about two chemicals

11. Intensive Properties Does NOT depend on the amount of matter present
AKA:
Boiling point
Density
Melting point
Conductivity
If you can identify the substance as a result of this property then it is an intensive property!

12. Extensive Property Does depend on the amount of matter present AKA:
Volume
Mass
Length

13. Intensive? or Extensive?
___________Shape
___________Density
___________Magnetism
___________Boiling Point
___________Height
___________Mass
___________Flame Color (used to tell what elements are present in chemical solutions)
___________pH (how acidic or basic something is)
___________Size
