Would I be right to differentiate with respect to T and p separately?...

V = RT/p

dV = R/p - (RT)/(p^2)

**drwls**, Sunday, May 17, 2009 at 7:52amI think they mean

dV = (R/p) dT - (RT)/(p^2) dp

This satisfies the requirement that the partial derivative of (R/p) with respect to p equals the partial derivative of (RT)/(p^2) with respect to T.
