There is nitrogen gas at a temperature of 25°C and a pressure of 200 kPa in a well-insulated 100 lt container. This vessel is connected to a pipe through which carbon dioxide gas flows at a temperature of 90°C and a pressure of 600 kPa. The connecting valve is opened and the pressure in the container is filled with carbon dioxide until it reaches 400 kPa. Find the final temperature and total entropy change in the container using the constant specific heats approximation.,
