So when B increases, p decreases, or when P increases, V decreases and so on. And our constant depends on the temperature and the number of moles. So if temperature increases or its temperature changes or N changes, this constant will also change. In other words, the number that you get when you multiply D times P will also change. Now, suppose we have some gas or some sample of gas. And suppose we have one set of conditions and a second set of conditions.
