How did the ideal Gas Law originate?
1 Answer
The “Ideal Gas Law” developed over time from the experiments and formulas derived by several separate chemists.
It was first stated by Émile Clapeyron in 1834 as a combination of the empirical Boyle's law, Charles' law and Avogadro's Law.
Explanation:
The simplest complete form is the combined law form, or Ideal Gas Law.
It was derived by combining the relationships of each of the other general laws (Boyles Law (1627-1691), Charles' Law (1746-1823), Guy-Lussacs Law (1778-1850). The related Dalton’s Law (1766-1844) describes partial pressures.

The other primary one to remember is the relationship to moles: PV = nRT (Avogadro’s Law (1776-1856)). Here you need to be careful to use the correct “gas constant”, R, which has different values for different dimensions.
