A piston-cylinder assembly contains air at 400 K and 1 bar. Pressure is increased isothermally to 1.6 bar. The environment is at 1 bar and 300 K. (a) Determine the specific work and heat transfer associated with the process (kJ/kg), (b) Determine the change in specific entropy of the system (kJ/kg-K), (c) Determine the change of specific entropy of the environment (kJ/kg-K)
