Gases Flashcards
The absolute temperature of a gas is directly proportional to the pressure if the volume remains constant.
Gay-Lussac’s law
The volume of a gas is inversely proportional to the pressure applied to it if the temperature remains constant.
Boyle’s law
The total pressure of a mixture of gases is equal to the sum of the partial pressures of each component gas.
Dalton’s law of partial pressures
Under conditions of constant temperature and pressure, equal volumes of gases contain equal amount of molecules.
Avogadro’s principle
The volume of a gas is directly proportional to its absolute (Kelvin) temperature if the pressure remains constant.
Charles’ law
Under conditions of constant temperature and pressure, the ratios of the volumes of gases that react are small whole numbers.
Gay-Lussac’s law of combining volumes
The pressure, volume, and temperature of a gas are all related if the quantity of gas remains constant.
Combined gas law

A table of __________ makes it possible for the chemist to compensate for the added pressure of water that evaporates during the water displacement process and mixes with the collected gas.
Partial pressures
All gases contain the same number of _________ if they have the same volume, pressure, and temperature.
