Express the volume expansivity and the isothermal compressibility as functions of density p and its partial derivatives.

Question:

Express the volume expansivity and the isothermal compressibility as functions of density p and its partial derivatives. For water at 50(C and 1 bar, K = 44.18 ( 10-6 bar-1. To what pressure must water be compressed at 50 C to change its density by 1%? Assume that K is independent of P.
