1. Intentions for success:
We will be successful when we describe the chemical and physical properties of matter.
Sept. 5, 2018
Vocab: chemical property,
Warm up: What are three types of common evidence that a chemical change has occurred? formation of precipitate

2. Ch. 9 - Classification of Matter
I. Describing Matter (45-62)
Physical Property
Physical Change
Chemical Change
Chemical Property

3. A. Physical Property
A characteristic of a substance that can be observed without changing its identity.
can be used to separate mixtures
EX: magnetism, density

4. A. Physical Properties
Examples: magnetism, density, Viscosity, Conductivity, Malleability, Hardness, melting point, boiling point, filtration, distillation, insulator
Silicon dioxide is solid at room temp, Methanol is a liquid. Which has the higher melting point?

5. B. Physical Change
A change in the form of a substance without changing its chemical makeup.
properties remain the same
reversible
can be used to separate mixtures
EX: dissolving, grinding, filtering

6. C. Chemical Change A change in the chemical identity of a substance.
properties change
irreversible
Signs: color change, formation of a gas/solid, release of light/heat
EX: burning, rusting

7. D. Chemical Property
A characteristic that indicates whether a substance can undergo a specific chemical change.
EX: flammability, reactivity

Flammability

9. Review Questions
How can knowing physical properties of matter be useful?
What allows mixtures to be separated by distillation?
Tell me about an oven mitt. What properties does it have?
