1. Gases

2. Kinetic Molecular Theory 1)Gases are made of tiny atoms with a lot of space in between them 2)These gas particles are in constant motion, colliding with each other and the walls of their container.

3. Kinetic Molecular Theory

4. 4 Unique Properties of Gases Property of Gases What that means 1 2 3 4 Ability to FlowCan be poured Low densitySmall mass, big volume CompressibleSqueezable Indeterminate Shape Expand or contract to fill container

5. Pressure Pressure – comes from randomly moving molecules hitting the surface of a container

6. Temperature Temperature – comes from motion of molecules - Faster molecules means higher temperature

7. Boyle’s Law Increase pressure, volume decreases Increase volume, pressure decreases

8. Charles’s Law Increase temperature, volume increases

9. Gay-Lussac’s Law Increase temperature, pressure increases Increase pressure, temperature increases
