<h3>
Boyle's law</h3>
Boyle's law states that the volume of a given mass of a gas is inversely proportional to its pressure provided that temperature remains constant.
P₁V₁ = P₂V₂
where;
- P₁ = 30 psi
- V₁ = 0.35 liters
- P₂ = 1 atm = 14.7 psi
The volume of the gas expansion is calculated as follows;
