| Question | Answer |
|---|---|
| diffusion | spontaneous mixing of the particles of two substances caused by their random motion |
| effusion | a process by which gas particles pass through a tiny opening |
| elastic collision | a collision between gas particles and between gas particles and container walls in which there is no net loss of kinetic energy |
| fluid | a substance that can flow and therefore take the shape of its container, a liquid or a gas |
| ideal gas | an imaginary gas that perfectly fits all the assumptions of the kinetic molecular theory |
| kinetic-molecular theory | a theory based on the idea that particles of matter are always in motion |
| real gas | a gas that does not behave completely according to the assumption os the kinetic molecular theory |
| atmosphere of pressure (atm) | exactly equivalent to 760 mm Hg |
| barometer | a device used to measure atmospheric pressure |
| millimeter of mercury (mm of Hg) | a common use of pressure |
| newton | the SI unit for force, the force that will increase the speed of a one kilogram mass by one meter per second each second it is applied |
| pascal | the pressure exerted by a force of one newton acting on an are of one square meter |
| kilopascal | equal to 1.013 x 10 ^5 |
| pressure | the force per unit area on a surface |
| standard temperature and pressure (STP) | the agreed upon standard conditions of exactly 1 atm pressure and 0 degrees cecius |
| standard ambient temperature and pressure (SATP) | equal to one bar |
| torr | equal to 1 mm Hg |
| absolute zero | the temperature -273.15 degree Celsius given a value of 0 in the kelvin scale |
| Kelvin | the temperature at which all thermal motion ceases |
| Boyle’s Law | the volume of a fixed mass of gas varies inversely with pressure at constant temperature |
| Charles’s Law | the volume of a fixed mass of gas at constant pressure varies directly with the kelvin temperature |
| Combined gas law | the relationship between the pressure, volume, and temperature of a fixed amount of gas |
| Dalton’s Law of partial pressure | the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases |
| Gay-Lusscac’s Law | the pressure of a fixed mass of gas at constant volume varies directly with the kelvin temperature |
| Ideal gas law | the mathmatical relationship of pressure volume temperature and the number of moles of a gas |
| Partial pressure | the pressure of each gas in a mixture |
| Avogadro’s Law | equal volumes of gases at the same temperature and pressure contain equal numbers of molecules |
| van der Waals equation | equation that relates the behavior of real gases to those of ideal gases |
| bar | |
| Gas Constant |
