7. TYPES OF MIXTURES: HETEROGENEOUS or HOMOGENEOUS 1. not uniformly mixed
2. after time the substances may settle
3. liquids are immiscible
HOMOGENEOUS
1. uniformly mixed
2. can not easily be separated
3. liquids are miscible
4. Store milk that has been homogenized
4. Fresh milk from a cow
5. Orange juice with pulp
5. Soda

8. Pure Substance or Mixture???

9. 2.2 MATTER AND ENERGY

10. the KINETIC MOLECULAR THEORY states:
All matter is made of atoms or molecules
Atoms and molecules are always in motion.
Particles that are warmer or less massive move faster than colder or heavier particles.

11. The Kinetic Molecule - Quiz
Molecules move by:
A. Forces acting on them
B. Their own internal energy
C. Both of the above
Cold causes molecules to:
A. Move slower
B. Lose energy
Heat causes molecules to:
A. Move faster
B. Gain energy

12. Properties of the STATES OF MATTER are:
State of Matter
Shape
Volume
Energy
GAS
LIQUID
SOLID

13. THE AMOUNT OF ENERGY DETERMINES THE STATE OF MATTER
SOLID LIQUID GAS
MORE attraction between molecules LESS
LESS energy MORE
RELEASED energy is ABSORBED

14. CHANGES OF STATES OF MATTER
GAS
LIQUID
SOLID
GAS
SUBLIMATION
SOLID
CONDENSE
EVAPORATE
FREEZE
MELT

15. Graphing Change of State

16. Graphing Change of State

17. HOW CHANGE OF STATE AFFECTS MATTER:
AMOUNT OF MASS ? ______
KIND OF MOLECULE ? ______
NUMBER OF MOLECULES? _____
VOLUME (space needed)? ______

18. God’s law of CONSERVATION:
MASS and ENERGY cannot be ____________ or ____________

19. REVIEW ENERGY MATTER SOLID LIQUID GAS KINETIC MOLECULAR THEORY
LOW ENERGY
MEDIUM ENERGY
HIGH ENERGY

20. 2.3 TWO PROPERTIES OF MATTER:
CHEMICAL PHYSICAL
How it reacts 1. Change of state
Burn, decay, rust…. 2. Density, boil, cut, dissolve
Form new substances 3. NO new substance 4.

21. REVIEW CHANGES IN GOD’S WORLD CHEMICAL PHYSICAL REACTIONS
DECAY / RUST / GROW
MELT / BOIL / CUT / CRUSH

22. AND GOD ESTABLISHED TWO LAWS TO GOVERN ALL MATTER
_________
__________
