Gay Lussac Law
Relate pressure and temperature at constant volume.
P₁ / T₁ = P₂ / T₂
Formula Explanation
Pressure of a fixed amount of gas is directly proportional to absolute temperature at constant volume.
Variables Explained
P = pressure; T = temperature in kelvin.
Solved Example
Pressure 2 atm at 300 K. Find pressure at 450 K.
P₂ = 2 × 450 / 300 = 3 atm.
