5.19 Boyle's Law

5.19 use the relationship between the pressure and volume of a fixed mass of gas at constant temperature:

                 p₁V₁ = p₂V₂

p₁ = Pressure at the beginning [kPa, bar or atm]

V₁ = Volume at the beginning [m³ or cm³]

p₂ = Pressure at the end [kPa, bar or atm]

V₂ = Volume at the end [m³ or cm³]

(Note: can use any units for V and p as long as they are the same at the beginning and end)
