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. So whenever we increase volume, we increase temperature. Or if we decrease volume, we must decrease the temperature for this guy to remain constant. Now notice this constant remains or depends on two things on the pressure and on the number of molecules.
