QUESTION 1(a) The air inside a 0.2 m² piston-cylinder device initially at 600 kPa. After heated up for 5 minutes, the airpressure increases to 1200 kPa, while maintaining the same volume due to installation of stopper in thepiston-cylinder.i.ii.iii.Calculate the boundary work experienced by this piston-cylinder device, kJ.Name the thermodynamics process.In the other case, if there is no stopper in the cylinder, the air inside the piston-cylinder deviceis allowed to expand to 0.35m' under isobaric condition of 600 kPa. Calculate the boundarywork, kJ.

A piston-cylinder arrangement contains water at 110°C, 87% quality with a volume of 1 L. What is the initial mass, in grams? The system is then heated, causing the 150-mm- diameter piston to rise and encounter a linear spring with k = 800 kN/m. Calculate the specific internal energy (kJ/kg) at this instant knowing that the measured volume is 1.7 L. The heating continues and compresses the spring in the process. When the piston encounters the stops, the pressure is 200 kPa. What is the temperature (in °C) and entropy (in kJ/kg-K) at this point? Heating then continues until the pressure reaches 300 kPa. What is the volume, in L, at this instant? Illustrate the complete process in separate P-v and T-v diagrams. Hint: Draw the FBD of the piston in each state. wwwwwww D=0.15m H₂O
