One kilogram of water (V1 = 1.003 cm3 kg-1) in a piston / cylinder device at 25oC and 1 bar is compressed in a mechanically reversible, isothermal process to 1.500 bar. Determine Q, W. (U, (H, and (5 given that ( = 250 ( 10-6 K-1 and K = 45 x 10-6 bar-1. A satisfactory assumption is that V' is constant at its arithmetic average value?
