What was discovered
At constant pressure all gases expand in the same proportion with temperature, which suggests an absolute zero when extrapolated. Together with Boyle's law it leads to the ideal gas equation.
Gay-Lussac honestly attributed the observation to Charles; Dalton also published it in 1801.
What it led to
- Equation of state of the ideal gas (Clapeyron, 1834)
- Absolute temperature scale
- Kinetic theory
- Thermodynamics of gases
Built on
- Boyle's law1662
- Charles's unpublished experiments (1787)
- Amontons's law (1702)
Made possible
- Avogadro's law1811
- Gas thermometer
- Calculated hot-gas balloons
