How It Works

Charles's Law

At constant pressure, the volume of a gas is directly proportional to its absolute temperature.

Formula

V1 / T1 = V2 / T2

Temperature must be in Kelvin. Heating a gas causes it to expand.

Worked Example

10 L of gas at 300 K heated to 600 K at constant pressure.

v1 = 10t1 = 300t2 = 600
  1. 01V1/T1 = V2/T2
  2. 02V2 = V1 * T2 / T1
  3. 03V2 = 10 * 600 / 300
  4. 04V2 = 20 L
