QUESTION 1 (a) The air inside a 0.2 m² piston-cylinder device initially at 600 kPa. After heated up for 5 minutes, the air pressure increases to 1200 kPa, while maintaining the same volume due to installation of stopper in the piston-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 device is allowed to expand to 0.35m' under isobaric condition of 600 kPa. Calculate the boundary work, kJ.
