the idea that particles of matter are always in motion 


an imaginary gas that perfectly fits all the assumptions of the kineticmolecular theory 


one in which there is no net loss of kinetic energy 


the flow of liquids and gases 


spontaneous mixing of the particles of two substances caused by their random motion 


a process by which gas particles pass through a tiny opening 


a gas that does not behave to the assumptions of the kineticmolecular theory 


the force per unit area on a surface 


the force that will increase the speed of a one kilogram mass by one meter per second each second it is applied 

millimeters of meucury(mm Hg) 




atmosphere of pressure(atm) 



the pressure exerted by a force of one newton (1 N) acting on an area of one square meter 

standard temperature and pressure(STP) 

for purposes of comparision standard conditions of exactly 1 atm and 0 degrees 


simple mathematical relationships between the volume, temperture, pressure,and the amount of a gas 


states the volume that the volume of a fixed mass of gas varies inversely with the pressure at cconstant temperture 


the temperture 273.15degrees 


the volume of a fixedmass of gas at constant pressure varies directly with the kelvin temperture 


a device used to measure atmospheric pressure 


pressure of a fixed mass of a gas at constant volume varies directly with the kelvin temperture 


the relationship between pressure, volume, and temperture of a fixed amount of gas 


pressure of gas in each mixture 

daltons law of partial pressures 

the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
