1. STATES OF MATTER MATTER UNIT

2. MATTER ANYTHING THAT HAS MASS AND TAKES UP SPACE.

3. KINETIC ENERGY EXPLAINS HOW PARTICLE IN MATTER BEHAVE.  ALL MATTER IS COMPOSED OF PARTICLES  PARTICLES ARE IN CONSTANT, RANDOM MOTION  PARTICLES COLLIDE WITH EACH OTHER AND WALLS OF THE CONTAINERS.

4. STATES OF MATTER StateCharacteristicsParticles Solid Definite shape and definite volume Closely packed in geometric arrangements Liquid Indefinite shape and definite volume Have more space and slide past each other Gas Indefinite shape and indefinite volume Have energy to spread out evenly in a container Plasma High temperature gasPositively and negatively charged

6. THE STATE OF MATTER DEPENDS ON TEMPERATURE TEMPERATURE  RELATED TO THE AVERAGE KINETIC ENERGY OF AN OBJECTS ATOMS OR MOLECULES. THERMAL EXPANSION  INCREASE IN THE SIZE OF A SUBSTANCE WHEN THE TEMPERATURE INCREASES AND CONTRACTS WHEN COOLED. EXCEPTION TO RULE: WATER-EXPANDS WHEN COOLED.

8. STATES OF MATTER DIAGRAM COMPLETE AS A CLASS

9. CHANGES IN STATES OF MATTER MELTING: SOLID  LIQUID MELTING: CHANGE FROM A SOLID STATE TO A LIQUID STATE. MELTING POINT: TEMPERATURE AT WHICH A SOLID MELTS.

10. CHANGES IN STATES OF MATTER FREEZING: LIQUID  SOLID FREEZING : CHANGE FROM A LIQUID STATE TO A SOLID STATE. FREEZING POINT: TEMPERATURE AT WHICH A LIQUID FREEZES.

11. CHANGES IN STATES OF MATTER VAPORIZATION: LIQUID  GAS VAPORIZATION: CHANGE FROM A LIQUID STATE TO A GASEOUS STATE. BOILING POINT: TEMPERATURE AT WHICH LIQUID BEGINS TO VAPORIZE. Evaporation can occur at surface of liquid without heating liquid.

12. CHANGES IN STATES OF MATTER CONDENSATION: GAS  LIQUID CONDENSATION: CHANGE FROM A GASEOUS STATE TO A LIQUID STATE. CONDENSATION POINT: TEMPERATURE AT WHICH A GAS CONDENSES.
