A steel piston/cylinder of 1 kg contains 2.5 kg ammonia at 50 kPa,20C. Now it is heated

Question:

A steel piston/cylinder of 1 kg contains 2.5 kg ammonia at 50 kPa,−20◦C. Now it is heated to 50◦Cat constant pressure through the bottom of the cylinder from external hot gas at 200◦C, and we assume the steel has the same temperature as the ammonia. Find the heat transfer from the hot gas and the total entropy generation.
