| Question | Answer |
|---|---|
| force per unit area acting on a surface | pressure |
| SI unit of force; force that will increase the speed of a 1 kg mass by 1 m/s for each second that it is applied | Newton |
| device used to measure atmospheric pressure | barometer |
| common unit of pressure | millimeters of mercury; mm Hg |
| exactly equivalent to 760 mm Hg | atmosphere of pressure |
| pressure exerted by a force of 1 Newton acting on an area of one square meter | Pascal |
| the pressure of each gas in a mixture | partial pressure |
| the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases | Dalton's Law of Partial Pressures |
| volume of a fixed mass of a gas at constant temperature varies inversely with pressure | Boyle's Law |
| temperature of -273.15 degrees Celsius, given a value of zero on the Kelvin scale; temperature at which the motion of all particles stops | absolute zero |
| volume of a fixed mass of a gas at constant pressure varies directly with the Kelvin temperature | Charles' Law |
| the pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature | Gay-Lussac's Law |
| relationship between the temperature, pressure, and volume of a fixed amount of gas | combined gas law |
| at constant temperature and pressure, the volumes of gaseous reactants and products can be expressed as ratios of small whole numbers | Gay-Lussac's Law of Combining Volumes of Gases |
| equal volumes of gases at the same temperature and pressure contain equal numbers of molecules | Avogadro's Law |
| the volume occupied by one mole of a gas at STP | standard molar volume of a gas |
| the mathematical relationship among pressure, volume, temperature, and the number of moles of a gas | ideal gas law |
| in the ideal gas law equation, it is R | ideal gas constant |
| the rates of effusion of gases at the same temperature and pressure are inversely proportional to the square roots of their molar masses | Graham's Law of Effusion |
