3. A system consisting of 12 m3 of water vapor and 0.005 m3 liquid water initially at 80C is heated to saturated vapor at constant pressure. The water is then heated at constant volume to a temperature of 200C. a) Determine the pressure and the specific volume at the initial state. (7 marks) b) Find the pressure at the final state. (6 marks) c) Find the change in volume for the process
