A piston-cylinder device with a set of stops initially contains 0.6 kg of steam at 1.0 MPa and 400∘C. The location of the stops corresponds to 40 percent od the initial volume. Now the steam is cooled. Determine the compression work if the final state is
(a) 1.0 MPa and 250∘C and
(b) 500 kPa.
(c) Also determine the temperature of the final state in part b.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
