Formulas and Key Relations
Avogadro's Law and Combined Gas Equation
Combined gas equation
P₁V₁/T₁ = P₂V₂/T₂ combines all three laws
Key relations
At constant temperature, volume of a fixed mass of gas is inversely proportional to pressure: V ∝ 1/P or PV = k (constant).
At constant pressure, volume of a fixed mass of gas is directly proportional to absolute temperature: V ∝ T or V/T = k.
Formula
V₁/T₁ = V₂/T₂.
Combines all gas laws
PV/T = k (constant).
For changing conditions
P₁V₁/T₁ = P₂V₂/T₂.
