Dalton's Law

Law¹

$n$ Let’s consider a mixture of gases composed of ▷eq.◁ different types of molecules. The total pressure of this gas mixture is equal to the sum of the pressures of each individual gas.

$$ p = \sum \limits_{i=1}^{n}N_{i} k_{B} T = \sum \limits_{i=1}^{n}p_{i} $$

Explanation

This law was named after the British chemist John Dalton (1766~1844).
