An insulated tank that contains 1 kg of O2 at 15°C and 300 kPa is connected to a 2-m3 uninsulated tank that contains N2 at 50°C and 500 kPa. The valve connecting the two tanks is opened, and the two gases form a homogeneous mixture at 25°C. Determine
(a) The final pressure in the tank,
(b) The heat transfer, and
(c) The entropy generated during this process. Assume T0 = 25°C.
