A steam-powered lift system (figure) leverages steam flowing through a pipeline at 1 MPa and 400°C to lift objects using a simple piston-cylinder configuration. To lift an object, it is placed on the piston and then the throttling valve is opened. Steam slowly flows into the well-insulated cylinder from the pipeline and lifts the object to the desired height, after which the valve is shut. The massless piston has a cross-section of 100 cm² and the atmospheric pressure is 100 kPa. A. If the cylinder is initially evacuated, what is the final temperature of the water in the cylinder after lifting a 2 kN object? B. How much water, in kg, is needed to lift the 2 kN object 10 m? m Steam line
