A400 l closed rigid tank initially contains 2.06 kg of saturated liquid-vapor mixture of water at 50c (state 1). heat transfer occurs slowly to the tank until the final state is either saturated liquid or saturated vapor (state 2). (a) determine whether the final state is saturated liquid or saturated vapor. justify your answer with appropriate calculation. (b) calculate heat transfer (kj) during the process. (c) show the heating process on p-v diagram. label states, show property values, and indicate appropriate lines of constant temperature. (d) will the final state be saturated liquid or saturated vapor if the tank volume were to be 4 l? justify your answer with appropriate calculation.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
