Boyle’s Law

- at constant temperature for a mixed mass, the absolute pressure and volume of a gas are inversely proportional

Charles’s Law

- when the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly related

GayLussac’s Law

- the pressure of a fixed amount of gas at constant volume is directly proportional to its temperature

Combined Gas Law

- combines Boyle’s, Charles’s, and GayLussac’s Laws into one

- when the amount of gas is kept constant, this law describes the relationship between pressure, volume, and temperature

Ideal Gas Law

- combines the separate gas laws into one equation that allows to solve for all variables
