Problem 1 A piston/cylinder contains 0.5 kg water at 50C with volume 0.1 m (state 1). By mistake someone locks the piston, preventing it from moving while the water is heated to saturated vapor (state 2). Find the following: (a) The phase description of the water in state 1. If applicable, find the quality. (b) The temperature of state 2. (c) The boundary work (in kJ). (d) The heat required (in kJ). Clearly indicate the direction of heat transfer. (e) Draw the process on a P-v diagram.
