Question

A spring-loaded piston is loaded with water at 200 kPa and 100°C, with a volume of 0.005 m³.The water is heated until the pressure is 400 KPa, at which point

the volume measures approximately 0.1 m². A. Calculate the mass of water in the piston (5 points): B. Sketch the process in a P-v diagram, indicating both states with respect to the saturation lines. Make sure to show the constant temperature lines as well. (10 points) C. Calculate the boundary work done during the process (10 points): D. Determine the amount of heat transfer (10 points):
