What are the basic gas laws?

Boyle's Law (P1V1=P2V2) and Charles's Law (V1/T1=V2/T2) describe how the pressure, volume, and temperature of a gas are related.

V2 (Volume)

These two laws describe how gases behave under different conditions of pressure, volume, and temperature.

Boyle's Law (P1V1 = P2V2): States that the pressure and volume of a gas are inversely proportional at a constant temperature.
Charles's Law (V1/T1 = V2/T2): States that the volume and absolute temperature of a gas are directly proportional at a constant pressure.

Important: Temperature must always be in Kelvin (K) for Charles's Law calculations.
