    Absolutely true.

    However, in just this one case, Wiki has a small error in the equation they provide. That equation is missing a minus sign. It should read :

    [tex] K= -V~ \frac { \Delta P}{\Delta V} [/tex]


    [tex]\Delta P \equiv P_{final} - P_{initial} [/tex]

    [tex]\Delta V \equiv V_{final} - V_{initial} [/tex]

    Still, this has taken half a day, for something that can be found in less than 5 minutes using Google. But this way, you have to do no work.

    The sign error has been corrected.
