Gas laws

Variation of pressure with volume (Boyle's Law)
The pressure of a fixed mass of gas is inversely proportional to its volume as long as its temperature remains constant.
Pressure (P) = constant/volume(V) space P1V1=P2V2

Variation of pressure with temperature (Pressure Law)
The pressure of a fixed mass of gas is directly proportional to its absolute temperature as long as its volume remains constant.
Pressure (P) = constant x absolute temperature (T) space
P1/ T1= P2/ T2

Variation of volume with temperature (Charles' Law)
The volume of a fixed mass of gas is directly proportional to its absolute temperature as long as its pressure remains constant.
Volume(V) = constant x absolute temperature (T) space
V1/T1= V2/T2
