Boyle's law
for a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure
Charles's law
the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant
combined gas law
the law that describes the relationship amoung the pressure, temperature, and volume of an enclosed gas
compressibility
a measure of how much the volume of matter decreases under pressure
Dalton's law of partial pressures
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 gas
diffusion
the tendancy of molecules to move toward areas of lower concentration until the concentration is uniform throughout
effusion
the process that occurs when a gas escapes through a tiny hole in its container
Gay-Lussac's law
the pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant
Graham's law of effusion
the rate of effusion of a gas is inversely proportional to the square root of its molar mass; this relationship is true for the diffusion of gases
ideal gas constant
the constant in the ideal gas law with the symbol R and the value 83.1 _________
ideal gas law
the relationship PV=nRT, which describes the behavior of an ideal gas
partial pressure
the contribution each gas in a mixture of gases make to the total pressure
