States of Matter, Kinetic Molecular Theory Read 9.1 (pages 418 – 420) 1. Are there larger attractive forces between molecules of gases, liquids, or solids? Explain. 2. Which state(s) of matter have these properties: a) definite shape, b) definite volume, c) takes the shape its container, d) incompressible. 3. Explain the properties of the three states of matter by referring to the forces that exist in each (e.g. “solids have intermolecular forces that are so strong that molecules are fixed in place. This gives solids a definite shape and volume. Solids are incompressible because their strong forces hold molecules tightly together, eliminating space between molecules.” Repeat for liquids & gases.)

4. What factor, in addition to strength of intermole- cular forces, affects the state of a substance? 5. Which theory deals with molecular motion? 6. What 3 types of motion can a molecule exhibit? Simply stated, what do these words mean? 7. What term means “the energy of motion”? What is an average measure of this? 8. A flask of O 2 (g) is heated from 10°C to 90°C. Are all O 2 molecules moving faster at 90°C? Explain. 9. Why does evaporation cause the temperature of a liquid to decrease? 10.Would a gas diffuse faster or slower in a
