Chemistry - Pressure
Several laws and terms to know
| Question | Answer |
|---|---|
| Boyle's Law | The volume of a given amount of gas held at a constant temperature varies inversely with the pressure. |
| Dalton's Law of Partial Pressure | The total pressure of a mixture of gases is equal to the sum of the partical pressures of the component gases. |
| Gay-Lussac's Law | The pressure of a given mass of gas varies directly with the Kelvin temperature when the volume remains constant. |
| Newton | SI unit for force |
| Combined Gas Law | A single law that states the relationship among pressure, volume, and temperature of a fixed amount of gas. |
| Ideal Gas | An imaginary gas whose particles are infinitely small and do not interact with each other. |
| Graham's Law of Diffusion | The rate of diffusion of a gas is inversely proportional to the square root of the gas's molar mass. |
| Ideal Gas Constants | It depends on the units that are used for pressure in the ideal gas equation. |
| Kinetic Molecular Theory | Model that is used predict gas behavior. |
| Pascal | SI unit for pressure. |
| Ideal Gas Law | Describes the behavior of an ideal gas in terms of the temperature, volume, and pressure and number of moles of a gas that are present. |
| Charles Law | The volume of a given given mass of gas is directly proportional to its Kelvin temperature at constant pressure. |
| Diffusion | The movement of particles from regions of higher density to regions of lower density. |
| Standard Temperature and Pressure | For a gas, is 0 degrees C and one atmosphere of pressure. |
| Avogadro's Law | Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. |
| Effusion | The passage of a gas under pressure through a tiny opening. |
| Partial Pressure | The pressure of each gas in a mixture. |
