Chapter 11 Vocabulary: The Behavior of Gases
| Question | Answer |
|---|---|
| Avogadro's Hypothesis | Equal volumes of gases at the same temperature and pressure contain equal numbers of particles. |
| Boyle's Law | For a fixed mass of gas atconstanttemperature, the volume of the gas varies inversely with pressure. |
| Charles's Law | The volume of a fixed mass of gas is directly proportionalto its Kelvin temperature if the pressure is kept constant. |
| Combined Gas Law | A relationship describing the behaviorof gases that combines Boyle's law, Charles' law, and GayLussac's law. |
| Dalton's Law of Partial Pressures | At constant volume and temperature, the total presure ofa mixture of gases is the sum of the partial pressuresof all the gases present. |
| Diffusion | The tendency of molecules and ions to move toward areas of lower concentration until the concentration is uniform througout the system. |
| Effusion | A process that occurs when a gas escapes through a tiny hole in its container. |
| Graham's Law of effusion | The rate of effusion of a gas is inversely proportional to the squareroot of its formula mass; this relationship is also true for the diffusion of gases. |
| Ideal Gas Constant | A term in the ideal gas law, which has the valuse 8.31 (LxkPa)/(Kxmol) |
| Ideal Gas Law | The relationship PxV=nxRxT, which descrives the behavior of an ideal gas. |
| Partial Pressure | The pressure exerted by each gas in a gaseous mixture. |
