Dry saturated steam at p1 = 3.5 MPa is contained in a cylinder-piston arrangement. It is brought into thermal contact with a heat sink at TR = 175K. The steam rejects Q12 = 16 MJ of heat during a constant pressure process. The mass of steam is m = 10 kg. Determine (a) final state ‘2’ of steam, (b) change in entropy of steam (∆S12), and (c) change in entropy of the universe (∆SU ).
