Boyle's Law / بويل القانون
P₁V₁ = P₂V₂
Example / Beispiel
Gas: 4L at 2 atm → pressure increases to 4 atm → V₂?
2 × 4 = 4 × V₂ V₂ = 2 L
Solving Variables
- P₂ = P₁V₁ ÷ V₂
- V₂ = P₁V₁ ÷ P₂
- P₁ = P₂V₂ ÷ V₁
- V₁ = P₂V₂ ÷ P₁
Applications
- Scuba diving
- Medical syringes
- Air compressors
- Lung breathing
Condition
Valid for ideal gases at constant temperature (isothermal process).
