And so it doesn't matter what type of gas you use, if it's large or small, it will have a volume of 22.4 liters. Now, this is according to experimental results. Once again, something we observe experimentally, we turn into a theory. And that's where our assumptions from our kinetic theory came. Let's look at Part D.
So earlier I said that for any given temperature and pressure, as long as they are held constant at that same temperature and pressure, our constant will always be the same. So suppose that's our case.
