Chemistry Chapter 14

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
