Boyle's law
States that at a constant temperature, the absolute pressure and the volume of a gas are inversely proportional. As pressure increases the gas value is reduced, as the gas value is reduced the gas volume increases.

States that at a constant pressure, the volume of a gas is directly proportional to the change in absolute temperature.
Dalton's Law
The total pressure of a mixture of gases is the sum of the individual pressures (Ptotal=P1+P2+P3...)
