Boyle's Law Calculator (P₁V₁=P₂V₂)
In an isothermal process, gas pressure is inversely proportional to volume: given the initial pressure/volume and one final quantity, solve the other (temperature constant).
Key points
Boyle's Law Calculator (P₁V₁=P₂V₂): In an isothermal process, gas pressure is inversely proportional to volume: given the initial pressure/volume and one final quantity, solve the other (temperature constant). Formula: P₁V₁ = P₂V₂ (isothermal process, T constant). Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Boyle's law: at constant temperature, the pressure of a fixed amount of gas is inversely proportional to its volume (P₁V₁ = P₂V₂). Applies to isothermal processes of an ideal gas; real gases deviate notably near liquefaction conditions.
