A cook filled a pressure cooker with 3 kg water at 20?C and a small amount of air and forgot about it. The pressure cooker has a vent valve, so if P > 200 kPa, steam escapes to maintain a pressure of 200 kPa. How much entropy was generated in the throttling of the steam through the vent to 100 kPa when half of the original mass escaped?
