Two tanks, A and B, are connected by a short section of pipe with a valve that is initially closed. Both tanks are insulated. Tank A initially contains air at 1.5 bars and 37 C in a volume of 30 L. Tank B contains air at 2.7 bars and 67 C in a volume of 10 L. The vale is open and the two gases are allowed to mix thoroughly until both the temperature and pressure are the same in both tanks. a) Determine the final temperature and pressure.
