Essential Question: How are temperature and kinetic energy related?

3. What is Matter?
Anything that has mass and takes up space.

4. The Law of Conservation of Mass:
Says that the mass of ALL substances present before a chemical change equals mass of ALL substance after the change.
MATTER CAN NOT BE CREATED NOR DESTROYED.

5. What does Kinetic mean? Resulting from motion.
Kinetic Energy: Energy that results from motion.

6. What is Kinetic Theory?:
Explains how particles in matter behave.
All matter is composed of particles

7. 2. Particles are in constant , random motion.

8. 3. Particles collide with each other and walls of their containers.

9. What are states of matter?
Solid
Liquid
Gas
Plasma

10. Do Now:

11. Solids Characteristics: Definite Shape and Definite Volume.
Particles: Closely packed in geometric arrangement.

12. Liquids Characteristics: Indefinite shape and definite volume.
Particles: Have more space and slide past each other.

13. Gases Characteristics: Indefinite shape and Indefinite volume.
Particles: Have energy to spread out evenly in container.

14. Plasma Characteristic: High temperature gas.
Particles: Positively and negatively charge.

15. Temperature The state of a sample of matter depends on Temperature.
Temperature: related to the average kinetic energy of an objects atoms or molecules.

16. Thermal Expansion:
When you buy soccer cleats do you buy your actual size or do you buy a size bigger or half a size bigger?
Definition: Increase in the size of a substance when the temperature increases and contracts when cooled.
Exception: Water- when cooled it expands.
