A200 liter tank is connected to a line flowing nitrogen (n2) at 30°c and 10 mpa pressure. the tank initially contains nitrogen (n2) at 30°c, 101 kpa. the valve is opened, allowing nitrogen to flow into the tank until the pressure inside is 9 mpa. at this point the valve is closed. this filling process occurs rapidly so that there is no heat transfer. for simplicity, you can treat nitrogen as an ideal gas with constant specific heats. a. what is the temperature of the nitrogen in the tank when the valve is closed? this is very similar to an example from class, except the tank isn't initially empty in this problem. b. the tank is then placed in storage where it eventually returns to the environment's temperature, 20 °c. what is the final pressure in mpa?
