Air is contained in a piston cylinder arrangement shown in the figure. Initially the air is
200 kPa and 20 oC while the piston rests on the lower stops. The air is heated, and the
piston starts to rise freely when the pressure reaches 250 kPa until the piston start to
encounter a linear spring when the volume is doubled. Heat is further added until the air
temperature reaches 1000 oC when the volume is triple the initial volume. Considering air
as ideal gas:
a- What is the final pressure?
b- Find the specific work done during the whole process.
c- Draw the process on a p-v diagram indicating the properties at all states
