A piston$$cylinder device initially contains $0\mathrm{.}6$ m$3$ of$$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 $1\mathrm{.}2$ m$3.$Use the data from the steam tables.The final temperature is $$C$.$
