5. Properties of Matter
Pg. 2-3

6. Matter Anything that has mass and volume Mass A measure of the amount of matter Volume The amount of space an object takes up

7. Substance- form of matter with uniform and unchanging composition Physical properties- substance keeps its chemical composition Chemical properties- substance changes the chemical composition

8. Complete paragraph at top of page 2 and Complete # 1-14 on pg. 2

9. States of Matter
1. solid - definite shape, definite volume, particles packed tightly
a. crystalline- regular repeating pattern
b. amorphous – without pattern, unorganized; ex: glass, plastic, wax
2. liquid - no definite shape, definite volume, close particles, but free flowing
gas - no definite shape or volume,
particles far apart
4. plasma - exists only at high temperatures expands to fill its container

10. Complete #12-22 on pg. 3

11. Physical vs. Chemical Changes
Physical Change
changes the form of a substance without changing its identity
Intensive properties remain the same, extensive will change
Chemical Change (chemical reaction)
changes the identity of a substance
products have different properties

12. Indicators of chemical change
4 Signs of a Chemical Change (or reaction)
change in color or odor
formation of a gas (bubbles)
formation of a precipitate (solid)
change in light or heat

13. Physical and Chemical Changes

15. Classification of Matter
Why do we classify things?
It makes it easier to identify a specific substance

16. Classification of Matter
Why do we classify things?
Classify the items in your bag. Give each group a title and list what you included in each group.
(bag items: cup, dropper, nail, straw, paper clip, ruler, penny, toothpick, wood ball, wood splint, plastic cylinder)

17. Why don’t we classify matter according to states?
This groups substances with different properties together
Ex. Salt, ice

18. Classify Chemicals Classify your chemicals into 2 groups
Now, split those two groups into three groups
Now, split one of the solids into two groups

19. Homogeneous mixture-has a constant composition throughout
Homogeneous mixture-has a constant composition throughout. You cannot see the particles. Also called Solutions Ex) salt water Heterogeneous mixtures- does not blend smoothly throughout. You can see the particles. Ex) Rocky Road Ice cream or italian salad dressing

20. Mixture vs. Pure Substance
a blend of two or more pure substances, each retains its own properties and composition, can be separated by physical means. Physically combined.
-homogeneous (solution) or heterogeneous
Pure Substance-
homogeneous sample of matter that has uniform composition and properties throughout the sample regardless of the source
- Elements and compounds are examples of pure substances

21. Element-pure substance that cannot be broken down by physical or chemical means Atom-simplest form of an element that retains its properties Compound-made up of two or more different elements that are combined chemically. Molecule-simplest form of a compound that retains its properties

26. Definitions
Law of conservation of mass- states that matter is neither created or destroyed
Chemical equation- a statement using chemical formulas to describe the identities and relative amounts of the reactants and products involved in the chemical reaction.
Reactants-the new substance formed in a chemical reaction
Products- the starting substance in a chemical reaction
