# What do the combined gas law relate?

Apr 23, 2017

$\frac{P V}{T} = k$

#### Explanation:

The combined gas law incorporates earlier gas laws, i.e. Charles's law, Boyle's law, and Gay-Lussac's law.

Given $\frac{P V}{T} = k$, where $k$ is some unspecified CONSTANT, then for equivalent quantities of gas then.......

$\frac{{P}_{1} {V}_{1}}{T} _ 1 = \frac{{P}_{2} {V}_{2}}{T} _ 2$...............

And as soon as we introduce Avogadro's law, we can access the Ideal Gas Law...
