1. Monday September 21, 2009 SWBAT identify 3 states of matter.
SWBAT distinguish between intensive properties and extensive properties.
SWBAT give examples of intensive and intensive properties of matter.

2. Warm Up DO THIS SILENTLY
Why is density an intensive property not an extensive property? Give an example of another intensive property.
What is matter?
What makes solids, liquids, and gas different?
Highlight of the weekend?

3. Everything that has mass and volume is called matter.
What is matter?
Everything that has mass and volume is called matter.
Basic definition of matter.

4. Intensive and Extensive Properties
Physical and chemical properties may be intensive or extensive.

5. What are intensive properties?
Intensive properties such as density, color, and boiling point do not depend on the size of the sample of matter and can be used to identify substances.

6. What are extensive properties?
Extensive properties such as mass and volume do depend on the quantity of the sample.

7. (And how the Kinetic Molecular Theory affects each)
States of Matter
(And how the Kinetic Molecular Theory affects each)
Solids
Liquids
Gases
Plasma
Others

8. States of Matter

9. Kinetic Molecular Theory
Solids
Have a definite shape
Have a definite volume
Kinetic Molecular Theory
Molecules are held close together and there is very little movement between them.

10. Liquids
Have an indefinite shape
Have a definite volume
Kinetic Molecular Theory:
Atoms and molecules have more space between them than a solid does, but less than a gas (ie. It is more “fluid”.)

11. Gases
Have an indefinite shape
Have an indefinite volume
Kinetic Molecular Theory:
Molecules are moving in random patterns with varying amounts of distance between the particles.

12. Plasma
Plasma is by far the most common form of matter. Plasma in the stars and in the tenuous space between them makes up over 99% of the visible universe and perhaps most of that which is not visible.

13. Exit Slip (Do On Back) What are the three (4) states of matter?
Which state of matter has indefinite shape but definite volume?
Give an example of an intensive property.
Give an example of an extensive property.

14. Lab Analysis Questions
Explain your method to find the thickness of your aluminum foil.
Based on your data, (refer to your data) which sample is thicker? Were your initial observations supported?
Compare your data to another group, are they similar, explain.
What may have been a sources of error?
