Chemistry
Combined Gas Law
Combine Boyle’s, Charles’ and Gay-Lussac’s laws.
P₁V₁ / T₁ = P₂V₂ / T₂
Formula Explanation
For a fixed amount of gas, PV/T remains constant.
Variables Explained
P, V, T = pressure, volume, temperature.
Solved Example
V₁=2 L, P₁=1 atm, T₁=300 K. Find V₂ at 2 atm and 400 K.
V₂ = (1×2×400)/(2×300) = 1.33 L.
