Water initially a saturated liquid at 95oC is contained in a piston-cylinder assembly. The water undergoes a process to the corresponding saturated vapor state, during which the piston moves freely in the cylinder. The change in state is brought about adiabatically by the stirring action of paddle wheel. Determine on a unit of mass basis, the (a) change in stored energy (ΔΦ), (b) the energy transfer accompanying work, (c) the energy transfer accompanying heat and (d) the energy destruction (I). Let T0 = 20oC and p0 = 1 bar.
