A piston/cylinder contains ammonia at 20C, quality 80%, and a volume of 10 L. A force is now applied to the piston so it compresses the ammonia in an adiabatic process to a volume of 5 L, where the piston is locked. Now heat transfer with the ambient takes place so the ammonia reaches the temperature of the ambient at 20C. Find the work and heat transfer. If it is done in a reversible process, how much work and heat transfer would be involved?
