# Using Boyle's law why is a graph showing the relationship between pressure and volume not linear?

#### Answer:

Well, what is $\text{Boyle's Law...?}$

#### Explanation:

$\text{Boyle's Law...}$, which is an EXPERIMENTAL gas LAW...holds that at constant temperature, and constant quantity of gas, $P \propto \frac{1}{V}$...where $\propto$ means $\text{proportional to....}$...

And so $P = \frac{k}{V}$...and $k = P V$...but this HOLDS for pressures and volumes given the STATED boundary conditions....

And thus the normal expression of $\text{Boyle's Law...}$, ${P}_{1} {V}_{1} = {P}_{2} {V}_{2}$....

And when we graph pressure against volume for a given quantity of gas at constant temperature....we gets...
