Problem 2 Calculate the amount of work and change in volume required to compress 10 kg of liquid water reversible from 10 to 400 bar at 60 C. Consider two cases: (a) The isothermal compressibility is given by C K = V(P +b) where c and b are functions of temperature only. At 60 C, b = 2700 bar and c = 0.125 cm3.g-1. (b) The isothermal compressibility is a constant (4.6x10-10 Park). Comment on the error in making the assumption of constant k
