for a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure
Boyle's law
the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant
Charles's law
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
Dalton’s law of partial pressures
the rate of effusion of a gas is inversely proportional to the square root of its molar mass; this relationship is also true for the diffusion of gases
Graham's laws of effusion
the pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant
Gay-Lussac's law
the relationship PV = nRT, which describes the behavior of an ideal gas
ideal gas law
the process that occurs when a gas escapes through a tiny hole in its container
effusion
the tendency of molecules to move toward areas of lower concentration until the concentration is uniform throughout
diffusion
the contribution each gas in a mixture of gases makes to the total pressure
partial pressure
a measure of how much the volume of matter decreases under pressure
