Atmosphere
The average pressure at sea level (101,325 Pa)
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
