Water, initially a saturated liquid at 140 oC, is contained in a piston-cylinder assembly. Thewater is heated to the corresponding saturated vapor state in an internally reversible process atconstant temperature and pressure. For a dead state at To= 20 °C and po= 1 bar, determine in kJ/kg:

(a) The change in exergy
(b) The exergy transfer accompanying heat
(c) The exergy transfer accompanying work
(d) The exergy destruction
