And what it says is that volume is directly proportional to temperature. And this means if we bring the T over or if we multiply a constant by T and we bring T over, what we get is the following v divided by T is equal to a constant. Remember, in Boyle's Law we saw that P times V gave us a constant and that if we increase pressure, our volume must decrease while keeping the constant the same. Well, in this case, we have the same kind of situation, except now we have volume divided by temperature. In other words. Now for this constant to remain a constant and not change if we increase volume, say by two, our temperature also must increase by the same amount by two.
