A two-phase mixture of steam and water with a temperature of 160 oC and a quality of 0.6 is contained in a piston-cylinder assembly. The mixture has a total mass of 0.9 kg, is compressed slowly and isothermally until only saturated liquid is present. What is the work done on the system?

Plot schematically the tensile stress versus strain curves for a typical thermoplastic material at a temperature below its glass transition temperature (tg and at a temperature above its tg, respectively. do the same for a typical thermosetting material. list in a table any differences or similarities between the two materials at t> tg and t < tg, respectively, and relate them to the structures of the two types of polymers
