Cards Term Kinetic-molecular theory Definition the idea that particles of matter are always in motion Term ideal gas Definition an imaginary gas that perfectly fits all the assumptions of the kinetic-molecular theory Term elastic collision Definition one in which there is no net loss of kinetic energy Term fluid Definition the flow of liquids and gases Term diffusion Definition spontaneous mixing of the particles of two substances caused by their random motion Term effusion Definition a process by which gas particles pass through a tiny opening Term real gas Definition a gas that does not behave to the assumptions of the kinetic-molecular theory Term pressure Definition the force per unit area on a surface Term newton(N) Definition the force that will increase the speed of a one kilogram mass by one meter per second each second it is applied Term millimeters of meucury(mm Hg) Definition common unit of pressure Term torr Definition 1 mm Hg Term atmosphere of pressure(atm) Definition 760 mm Hg Term pascal(Pa) Definition the pressure exerted by a force of one newton (1 N) acting on an area of one square meter Term standard temperature and pressure(STP) Definition for purposes of comparision standard conditions of exactly 1 atm and 0 degrees Term gas laws Definition simple mathematical relationships between the volume, temperture, pressure,and the amount of a gas Term boyle's law Definition states the volume that the volume of a fixed mass of gas varies inversely with the pressure at cconstant temperture Term absolute zero Definition the temperture -273.15degrees Term charles's law Definition the volume of a fixedmass of gas at constant pressure varies directly with the kelvin temperture Term barometer Definition a device used to measure atmospheric pressure Term gay-lussac's law Definition pressure of a fixed mass of a gas at constant volume varies directly with the kelvin temperture Term combined gas law Definition the relationship between pressure, volume, and temperture of a fixed amount of gas Term partial pressure Definition pressure of gas in each mixture Term daltons law of partial pressures Definition the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
