1 kg of saturated steam at 1000 kPa is in a piston-cylinder and the massless cylinder is held in place by pins. The pins are removed and the system suddenly and adiabatically expands to 5x its original volume before the piston hits a pair of upper pins. The expansion takes place against an atmosphere is 60 kPa. What is the final specific internal energy of the system? The answer will be in kJ/kg.
