A 10 cm thick piston sits inside a cylinder containing 0.1 kg of water. An internal flange is built into the cylinder and serves to stop the control volume from expanding. The mixture is expanded from an initial value of Vi = 0.82 m³ and Ti = 20 °C. The cross-sectional area of the piston is 1.43 m². a) Enough heat is added so that the piston just barely comes in contact with the flange. Determine the work done W₁₂ and heat added Q₁₂.
