A piston-cylinder device initially contains 0.6 m3 of saturated water vapor at 250 kPa. At this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 300 kPa is required to move it. Heat is now slowly transferred to the steam until the volume becomes 1.5 m3. Use the data from the steam tables. Determine the final temperature. (You must provide an answer before moving on to the next part.) The final temperature is °C.

Required information
A piston-cylinder device initially contains 0.6 m3 of saturated water vapor at 250 kPa. At this state, the piston is resting on
a set of stops, and the mass of the piston is such that a pressure of 300 kPa is required to move it. Heat is now
slowly transferred to the steam until the volume becomes 1.5 m3. Use the data from the steam tables.
Determine the final temperature. (You must provide an answer before moving on to the next part.)
The final temperature is
°C.
