Air is contained in a piston-cylinder arrangement initially at 1.2 bar and 300 K with a volume of 0.12 m3. Energy as heat of 11.82 Joules is transferred to the air in a quasi-equilibrium constant pressure process to yield a final temperature of 370.2 K. The piston moves without friction. Taking Cp = 1.005 kJ/kg and Cy = 0.72 kJ/kg K, determine the availability change for the process. The reference environment is at 298 K and 1.0135 bar.
