Boyle's & Charles's Law Calculator

Boyle's, Charles's, and Gay-Lussac's laws describe the relationships between pressure, volume, and temperature of a gas. The combined gas law unifies these relationships for changing conditions.

Key Laws & Formulas:

• Boyle's Law: P₁V₁ = P₂V₂ (constant T)
• Charles's Law: V₁/T₁ = V₂/T₂ (constant P)
• Gay-Lussac's Law: P₁/T₁ = P₂/T₂ (constant V)
• Combined Gas Law: P₁V₁/T₁ = P₂V₂/T₂

Units:

• Pressure: Pa, atm, bar, psi
• Volume: m³, L, mL
• Temperature: K, °C, °F (always convert to K for calculations)

Applications:

• Gas compression and expansion
• Breathing and respiration
• Weather balloons and atmospheric science
• Industrial gas storage and transport
• Refrigeration and air conditioning

Law Analysis:

• Boyle's Law: At constant temperature, pressure and volume are inversely proportional.
• Charles's Law: At constant pressure, volume and temperature are directly proportional.
• Gay-Lussac's Law: At constant volume, pressure and temperature are directly proportional.
• Combined Gas Law: Relates pressure, volume, and temperature for a fixed amount of gas.
