Boyle's Law: Pressure-Volume Relationship

Formula

P1 × V1 = P2 × V2

Boyle's Law states that for a fixed amount of gas at constant temperature, pressure and volume are inversely proportional: P1V1 = P2V2. Doubling the pressure halves the volume. This gas law is fundamental to understanding pneumatics, breathing, and atmospheric science.

Common use cases:

  • Scuba diving gas calculations
  • Syringe and piston problems
  • HVAC system design
