Kinetic Molecular Theory

Explains macroscopic properties of gases by considering their molecular composition and motion.

Avogadro's Law

Equal volume of gasses at the same temperature and pressure must contain the same number of moles, atoms, ions.

Partial Pressure

The pressure exerted by a single gas in mixture

Dalton’s Law

The total pressure of a mixture of gases must equal the sum of partial pressures of all component gases.

Diffusion

Molecules move from areas of high concentration to areas of lower concentration.

Graham’s Law

The rate of diffusion of a gas is inversely proportional to the square root of the gram molecular weight of the gas

Fick’s Law

The bulk movement of a gas through biological membrane

Henry’s Law

The amount of a given gas that dissolves in a given type of liquid is directly proportional to the partial pressure

Boyle’s Law

The volume of gas varies inversely with the pressure

Charles Law

The volume of gas varies directly with changes in temperature

Gay-Lussac’s Law

The pressure exerted by a gas varies directly with its absolute temperature.

Combined Gas Law

A combination of Boyle’s, Charles’ and Gay- Lussac's law.

Ideal Gas Law

A combination of Boyle’s, Charles's, Gay Lussac’s and adds Avogadro’s (gmw)
