CH301 2010 Worksheet 9 on Gases 1. What are the assumptions of Kinetic Molecular Theory? 2. For the following variable pairs, tell if they have directly proportional or inversely proportional relationships: a. V & T b. P & T c. n & P d. P & V 3. The ideal gas law can be used to solve for the molecular weight of an unknown gas. If 1 g of a hypothetical molecule at STP takes up 1 L of volume, what is the molecular weight of that molecule? 4. You should know that many gases do not behave ideally and therefore do not obey the ideal gas law. How do we correct for this in real life calculations when we need more accurate answers? 5. Describe the relationship between diffusion, effusion, and gas speed. 6. If two gas molecules have the same kinetic energy, which will move faster, the larger molecule or the smaller molecule? WHY? 7. As temperature increases, what happens to the average kinetic energy of the molecules in a gas? What would you expect to happen to the rate of diffusion and effusion? 8. Balloons will change size depending on room temperature. Explain why.
