In an experiment, a rigid container holds 3 kg of refrigerant-134a initially at 30°C and 180 kPa. The refrigerant is now cooled while being stirred until its pressure drops to 80 kPa. At the initial state, the specific entropy is |(to 4 d.p.) in (insert unit symbol), specific volume is (to 5 d.p.) in (insert unit symbol), At the final state, the specific volume is |(to 5 d.p.)(insert space then init symbol), the quality is (to 3 d.p.), the specific entropy is (to 3 d.p.)(insert space then init symbol) The entropy change of the refrigerant during this process is (to 3 d.p.) (insert space then init symbol). From the final answer, does the systen violates the second law of thermodynamics? (yes/no).

A piston-cylinder assembly contains 3 lb of water vapor, initially at 300F and 20 lbf/in2 is compressed isothermally to a volume of 14ft3 . The system is then heated at constant volume to a final pressure of 140 lbf/in2 . During the isothermal compression 600 Btu of heat is transferred to the surroundings. Kinetic and potential energy effects are negligible. Show the P-v diagram for both processes, calculate the total work done, and the total change in entropy.
A frictionless piston-cylinder assembly initially contains saturated liquid water at a pressure of 200 kPa. Then, 450 kJ of heat transfer occurs from a source with a temperature of 500 0C to water and some of the water evaporates at constant pressure. Show whether this state change is feasible or not by considering the increase of entropy principle.
