# How can partial pressure change?

Jun 30, 2017

By changing the volume of the container........

#### Explanation:

Or by changing the molar quantity of the gas under question. Or by increasing the temperature.......

All of this relates to the old Ideal Gas Equation.....

${P}_{1} = \frac{{n}_{1} R T}{V}$

Of course the addition of an inert gas to the container will NOT change ${P}_{1}$. Why not?
