A 10-m-high open cylinder, with Acyl = 0.1 m², contains 20◦C water above and 2 kg of 20◦C water below a 198.5-kg thin insulated floating piston, as shown in Fig. P3.107. Assume standard g, P₀. Now heat is added to the water below the piston so that it expands, pushing the piston up, causing the water on top to spill over the edge. This process continues until the piston reaches the top of the cylinder. Find the final state of the water below the piston (T, P, v) and the heat added during the process.
