2. An insulated tank that contains 1 kg 02 at 15C and 300 kPa is connected to a 2 m3 insulated tank that contains N2 at 50C and 500 kPa. The valve connecting the two tanks is opened, and the two gases form a homogenous mixture. Assume variable specific heats. Determine a) The final temperature in the tank. b) The final pressure in the tank. c) The entropy generated during the process.
