# What is the proper form of the combined gas law?

Apr 25, 2017

$\frac{P V}{T} = k \text{ (a constant)}$

#### Explanation:

$\frac{P V}{T} = k \text{ (a constant)}$

Since the constant won't change as long as your moles of gas remain the same, you get the formula:

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