Amass of 3 kg of water is contained in a freely moving piston- cylinder device such that the pressure remains 400 kpa. initially, 1.17kg is in the liquid phase and the rest is vapor. heat is added to the system until the temperature reaches 400°c. determine: a)- the initial temperature, in 0c b)- the initial volume in m^3 c)- the final volume, in m3. d)- the boundary work done, in k). е)- the amount of heat transfer, ink).
