A piston-cylinder assembly contains carbon monoxide modeled as an ideal gas with constant specific heat ratio, k 5 1.4. The carbon monoxide undergoes a polytropic expansion with n 5 k from an initial state, where T1 5 100°C and p1 5 300 kPa, to a final state, where the volume is twice the initial volume. Determine (a) the final temperature, in °C, and final pressure, in kPa, and (b) the work and heat transfer, each in kJ/kg.
