1. Objectives Properties and Changes in Matter
Be able to list physical and chemical properties
Be able to determine if it is a physical or chemical change

2. Physical Change
Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.
Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

3. Types of Physical Properties
Extensive: Size does matter and will change the result.
Volume
Mass
Intensive: Size does not matter or amount this will remain the same.
Density
Temperature
Color

4. Chemical Properties
The ability of a substance to undergo a chemical change.
Example:
Rusting
Burning
Chemical Reaction

5. Properties of matter:
Physical change - a change where new kinds of matter are not formed. No change in chemical formula
Examples:
Boiling Cutting Breaking

6. Phase Change
Deposition

7. Physical Change IT IS A PHYSICAL CHANGE BECAUSE 1. ITS SIZE CHANGED.
2. ITS SHAPE CHANGED.
3. IT IS A PHASE CHANGE:
FREEZING, MELTING, BOILING, SUBLIMING, EVAPORATING, OR CONDENSATION.

8. Phase Diagrams
Phase diagram – graph of pressure versus temperature that shows the condition required for a specific substance to undergo a phase change
Triple point – represents the temperature and pressure at which three phases of a substance can coexist
Critical point- max pressure and temperature the substance can exist as a liquid
C. Johannesson

9. Phase Diagrams - Water

10. What physical changes can happen to a paper clip?

11. Properties of matter:
Chemical change - a change where new kinds of matter are formed. Atoms are rearranged.
Examples:
Combustion Baking Rusting

12. Chemical Change IT IS A CHEMICAL CHANGE BECAUSE
1. A PRECIPITATE FORMED.
2. IT CHANGED COLOR
3. A GAS IS PRODUCED.(BUBBLING)
4. A TEMPERATURE CHANGE OCCURRED.
5. ODOR CHANGE
6. LIGHT PRODUCED.
