Carbon dioxide (CO)contained in a piston-cylinder arrangement, initially at 6 bar and 400 K, undergoes an expansion to a final temperature of 260 K, during which the pressure-volume relationship is ₚV¹² = constant. Assuming the ideal gas model for the CO₂, determine the final pressure, in bar, and the work and heat transfer, each in kj / kg.
Part A Assuming the ideal gas model for the CO₂. determine the final pressure, in bar.
