⚗️Boyle's Law Calculator (P₁V₁=P₂V₂)
Boyle's Law states that at constant temperature, the pressure of an ideal gas is inversely proportional to its volume. P₁V₁ = P₂V₂. Doubling the pressure halves the volume; halving the pressure doubles it.
- 1Record initial pressure P1 and volume V1
- 2Identify either the new pressure P2 or new volume V2
- 3Apply P1V1 = P2V2 to find the unknown
- 4Temperature must remain constant throughout
P1=1 atm · V1=10L · P2=2 atm=V2 = 5L(1×10)/2=5L; gas compressed to half volume

Fun Fact
Robert Boyle first published this law in 1662. He used a J-shaped glass tube with trapped air to demonstrate the pressure-volume relationship systematically.
