Terms | Definitions |
|---|---|
 Boyle's Law | for a given mass of gas at constant temperature, the volume of gas varies inversely with pressure. |
| Charles's Law | the volume of fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant. |
| Combined Gas Law | the law that describes the relationship among pressure, temperature, and volume of an enclosed gas. |
| Compressibility | measure of how much the volume of matter decreases under pressure. |
| Dalton's Law of Partial Pressure | at constant volume and temperature, the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases. |
| Diffusion | the tendency of molecules to move toward the areas of lower concentration until the concentration is uniform throughout. |
| Effusion | the process that occurs when a gas escapes through a tiny whole in its container. |
| Gay-Lussac's Law | the pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant. |
| Graham's Law of Effusion | the rate of effusion of gas is inversely proportional to the square root of its molar mass; this relationship is also true for the diffusion of gasses. |
| Ideal Gas Constant | the constant in the ideal gas law with the symbol R and the value of 8.31 L•kPa ⁄ K•mol or 0.08206 L•atm ⁄ mol •K. |
| Ideal Gas Law | the relationship PV=nRT, which describes the behavior of an ideal gas. |
| Partial Pressure | the contribution each gas in a mixture of gasses makes to the total pressure. |
