| compressibility | a measure of how much the volume of matter decreases under pressure |
| Boyle’s law | for a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure |
| Charles’s law | the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant |
| Gay-Lussac’s law | the pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant |
| combined gas law | the law that describes the relationship among the pressure, temperature, and volume of an enclosed gas |
| ideal gas constant | the constant in the ideal gas law with the symbol R and the value 8.31 (L·kPa)/(K·mol) |
| 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 gases makes to the total pressure |
| Dalton’s law of partial pressures | 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 areas of lower concentration until the concentration is uniform throughout |
