Water flows in a pipe at a pressure of 3.5 MPa and a temperature of 350 degrees Celsius. Attached to the pipe is an evacuated enclosure separated from the pipe by a valve. An impeller is used to thoroughly mix the contents of the enclosure. The valve is opened and 10 kg of steam is allowed to enter the enclosure. At the end of the process, the pressure inside the enclosure is found to be 3.5 MPa, and during the process, 700 kJ of impeller work is required to mix the contents. The enclosure has a volume of 0.15 m^3. Determine the final temperature(if superheated) or quality (if saturated) of the steam inside the enclosure.
