Question:

A mass of 0.02 kg of saturated water vapor is contained in the cylinder of Fig. 3.49. The spring with spring constant K = 60 kN/m just touches the top of the frictionless 160-kg piston. Heat is added until the spring compresses 10 cm. Estimate the final temperature of the steam, the work done, and the heat transfer required.
