Hi, I'm wondering what the physical meaning there is to taking the volume derivative of the equation pv=k.
d/dv [ pv = k ] (v * dp/dv ) + p = 0 I know this has to do with the elasticity of a gas but I am unsure as to why this process of deriving the equation pv = k was taken. Any help would be appreciated. Thanks

is that the derivation david bernouli used in hydrodynamics or whatever?
heres a derivation i thought was very accessable http://books.google.com/books?id=ist...=PA27&lpg=PA27

The equation is important because in this process....according to the ideal gas equation,the temperature remains constant....and thus the internal energy.
I hope this is what you asked......if not please elaborate a little more on what you mean........
