A cylinder fitted with a frictionless piston contains carbon dioxide at 500 kPa, 400 K, at which point the volume is 50 L. The gas is now allowed to expand until the piston reaches a set of fixed stops at 150 L cylinder volume. This process is polytropic, with the polytropic exponent n equal to 1.20. Additional heat is now transferred to the gas, until the final temperature reaches 500 K. Determine
a) The final pressure inside the cylinder.
b) The work and heat transfer for the overall process.
