Formulas and Key Relations

Boyle's Law - Pressure and Volume

Boyle's Law

at constant temperature and amount of gas, volume is inversely proportional to pressure (V ∝ 1/p)

Mathematical expression

p₁V₁ = p₂V₂ or pV = constant

Charles' Law - Temperature and Volume

Charles' Law

at constant pressure and amount of gas, volume is directly proportional to absolute temperature (V ∝ T)

Mathematical expression

V/T = constant or V₁/T₁ = V₂/T₂

Gay-Lussac's Law - Temperature and Pressure

Mathematical expression

p/T = constant or p₁/T₁ = p₂/T₂

Key relations

At constant temperature and amount of gas, the volume is inversely proportional to pressure: V ∝ 1/p or p₁V₁ = p₂V₂.

At constant pressure and amount of gas, volume is directly proportional to absolute temperature: V ∝ T or V₁/T₁ = V₂/T₂.

At constant volume and amount of gas, pressure is directly proportional to absolute temperature: p ∝ T or p₁/T₁ = p₂/T₂.
