🌬️ Boyle's Law Explained

P₁V₁ = P₂V₂  (T constant)

At constant temperature, the pressure and volume of a gas are inversely proportional. When pressure doubles, volume halves.

📖 Example

✅ Gas Compression

P₁ = 1 atm, V₁ = 10 L, P₂ = 4 atm. Find V₂.

V₂ = P₁V₁/P₂ = (1×10)/4 = 2.5 L

❓ FAQ

What is Boyle's Law?
Boyle's Law states that for a fixed amount of gas at constant temperature, pressure and volume are inversely proportional: PV = constant.
What are the units for pressure in Boyle's Law?
Any consistent pressure unit works (atm, kPa, mmHg, Pa) as long as P₁ and P₂ use the same unit. Similarly for volume (L, mL, m³).
