Boyle’s Law

The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies, assuming temperature and amount of gas remain unchanged.

Charles’s Law

The increase in gas temperature will cause the volume of the gas to increase if the volume is allowed to increase, while pressure remains constant.

Gay-Lussac’s Law

The increase in gas pressure is caused by the increase in gas temperature in a set volume container, with pressure increasing proportionally with temperature.

Avogadro’s Law

The increase in the number of moles of gas is directly proportional to the volume of gas, provided that temperature stays constant.

Ideal Gas

A theoretical gas that perfectly follows all gas laws under all conditions and does not condense when cooled.

Real Gas

Gases that do not follow ideal gas laws, where molecules stick together and fill a considerable amount of the total gas volume.

Critical Temperature

The temperature above which a gas cannot be liquefied.

Compressibility Factor (Z)

A factor used to describe how much a real gas deviates from ideal behavior, expressed in the equation PV = ZnRT.

Combined Gas Law

The formula P1V1T2 = P2V2T1 relates pressure, volume, and temperature of a gas, assuming no leakage and constant volume.

General Gas Law

A law that combines various gas laws to relate pressure, volume, and temperature.
