3.9 kPa is contained in a piston-cylinder arrangement. The steam is heated at constant pressure to 300C. Calculate the work done by the steam. Steam in the amount of 0.025 kg at a quality of 10 percent and a pressure of 200 kPa is heated in a rigid container until the temperature reaches 200C. Find (a) the final quality and (b) the work done by the steam. 3.10 The frictionless niston shown 1:1-
