Question: A vertical piston/cylinder has a linear spring mounted as shown so at zero cylinder volume a balancing pressure inside is zero. The cylinder contains 0.25

A vertical piston/cylinder has a linear spring mounted as shown so at zero cylinder volume a balancing pressure inside is zero. The cylinder contains 0.25 kg air at 500 kPa, 27oC. Heat is now added so the volume doubles.
a) Show the process path in a P-V diagram
b) Find the final pressure and temperature.
c) Find the work and heat transfer.
