An engine carries 1.00 mol of an ideal monatomic gas during thecycle consisting of: an ab isochoricprocess, then an adiabatic expansionprocess bc until reaching the original pressure andan isobaric process ca until reaching the initial state. Thetemperatures of the states are Ta = 300 K,Tb = 600 K, andTc = 455 K. (a) Draw thepV diagram (b) Determine the heat, internal energy change and thework in each process, and in the complete cycle. (c) If thepressure Pais 1.00 atm, findthe pressure and volume at states b andc. Use Patm =1,013x105 Pa and R =8,314 J/mol K.
