Avogadro's Law

A law stating that the volume (V) of a gas and the amount of the gas in moles (n) are directly proportional

Boyle's Law

A law maintaining that the volume (V) of a gas and its pressure (P) are inversely propertional

Charles's Law

A law stating that the volume (V) of a gas and its temperature (T) expressed in kelvins are directly proportional

Combined Gas Law

A law that combines Boyle's law and Charles's law

Ideal Gas Law

A law that combines the four properties of a gas - pressure (P), volume (V), temperature (T), and number of moles (n) in a single equation showing their interrelatedness

Kinetic Molecular Theory

A simple model for gases that predicts the behavior of most gases under many conditions

Pressure

The force exerted per unit are by gaseous molecules as they collide with the surfaces around them

Standard Temperature and Pressure (STP)

Conditions often assumed in calculations involving gases: T = 0°C and P = 1 atm
