In other words, if our pressure and temperature are the same, then our constant will always be the same. But if we increase or decrease our temperature or pressure, our constant will also change. So that brings up an interesting relation. That basically means as long as our pressure and temperature are the same, this will always be true for any volume or for any number of moles. This will always be our constant. And we'll see why this is important in Part D. Let's look at C for a second.
