===Meaning===
[[Boyle's Law]] states that for a fixed [[mass]] of [[gas]] at constant [[temperature]], the product of its [[pressure]] and [[Volume (Space)|volume]] is constant.
===About Boyle's Law===
*Expressed mathematically as 𝑃×𝑉=constant
*Describes the inverse relationship between the [[pressure]] and [[Volume (Space)|volume]] of a [[gas]].
*Assumes [[Ideal Gas|ideal gas]] behaviour.
*Applicable in various real-world scenarios such as breathing and syringes.
Where:
𝑃 is [[pressure]]
and
𝑉 is [[Volume (Space)|volume]]
===Examples===
*Compressing a [[gas]] in a piston decreases its [[Volume (Space)|volume]] and increases its [[pressure]].*In scuba diving, the [[pressure]] of air in tanks decreases as the diver uses the air and the [[Volume (Space)|volume]] increases.
