Gay-Lussac's Law describes how a gas's pressure rises with temperature when it's sealed in a fixed volume — think of a spray can warming up.
Gay-Lussac's Law describes how a gas's pressure rises with temperature when it's sealed in a fixed volume — think of a spray can warming up. This calculator solves for any one of pressure/temperature pair values from the other three.
A sealed can at 1 atm and 290 K is heated to 350 K. Leaving P2 blank: P2 = (1×350)/290 ≈ 1.21 atm.
At constant volume, the pressure of a gas is directly proportional to its absolute temperature: P1/T1 = P2/T2.
Like the other gas laws, this proportional relationship only holds using absolute (Kelvin) temperature, not Celsius or Fahrenheit.
An aerosol can warming up and building internal pressure — if heated enough, the rising pressure (at essentially constant volume) can cause it to rupture.
