A well-insulated, rigid tank, having a volume of 2 m3 , contains saturated water vapor at 120 ◦C. The water is stirred until the pressure is 3 bar. Determine the final temperature and the work required of the stirrer. (b) The container is compressed while allowing heat to escape, maintaining pressure as the fluid cools to saturated vapor. Determine the heat loss and work during this process. (c) The container is then cooled at constant volume to 1 bar. Determine the heat loss and quality of the resulting mixture
