(5.3) Characteristics of Gases

2. Four States of Matter

3. States of Water Solid, Liquid, and Gas

4. Plasma State Our Sun

5. Kinetic Theory of Matter (See the particles moving or vibrating in place)

7. Gases have neither definite shape nor definite volume.

8. Gas particles have frequent collisions due to very high speeds.

9. The average distance a gas molecule travels before colliding with another molecule is the mean free path of the molecule.

10. The speed, the distance of travel, and the number of molecular collisions vary with temperature, the number of particles in a given volume, and the mass of the particles.
