    About Gas Laws

    Gas laws describe the relationships between pressure, volume, temperature, and the amount of gas in a system. The ideal gas law combines Boyle's law, Charles's law, and Avogadro's law into a single equation: PV = nRT.

    •Key Concepts

    • –Ideal Gas Law: PV = nRT
    • –Combined Gas Law: P₁V₁/T₁ = P₂V₂/T₂
    • –Gas Constant R: 0.08206 L⋅atm/(mol⋅K)
    • –Temperature: Must be in Kelvin (K)

    •Individual Gas Laws

    • –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)
    • –Avogadro's Law: V ∝ n (constant P, T)
