Discuss the below in detail:
Q: A cylinder fitted with a frictionless piston contains 0.2 kg of saturated (both liquid and vapor present) R-12 at -20oC. The external force on the piston is such that the pressure inside the cylinder is related to the volume by the expression: P = - 47.5 + 4.0 x V1.5, kPa and L Heat is now transferred to the cylinder until the pressure inside reaches 250 kPa. Calculate the work and heat transfer.
