A piston-cylinder device initially contains ‘steam at 200

Chapter 4, Problem 35P

(choose chapter or problem)

A piston-cylinder device initially contains steam at \(200 \mathrm{kPa}, 200^{\circ} \mathrm{C}\), and \(0.4 \mathrm{~m}^{3}\). At this state, a linear spring \((F \propto x)\) is touching the piston but exerts no force on it. Heat is now slowly transferred to the steam, causing the pressure and the volume to rise to \(250 \mathrm{kPa}\) and \(0.6 \mathrm{~m}^{3}\), respectively. Show the process on a \(P\)-\(v\) diagram with respect to saturation lines and determine (a) the final temperature, (b) the work done by the steam, and (c) the total heat transferred.
