# How does the pressure of an combined gas change as temperature increases?

Jul 1, 2018

Well, what does old $\text{Charles' Law}$ say.....?

#### Explanation:

$\text{Charles' Law}$ holds that for a given quantity of gas...

$V \propto T$, i.e. $V = k T$, where $k$ is some constant of proportionality...and given constant pressure, i.e. the gas is enclosed in a piston...we solve for $k$ and get...

$\frac{V}{T} = k$...else....${V}_{1} / {T}_{1} = {V}_{2} / {T}_{2}$

$\text{Volume}$ changes proportionally with absolute temperature...
