A 1.2-m3 insulated rigid tank contains 2.13 kg of carbon dioxide at 100 kPa. Now paddle-wheel work is done on the system until the pressure in the tank rises to 120 kPa. Determine (a) the actual paddle-wheel work done during this process and
(b) Te minimum paddle-wheel work with which this process (between the same end states) could be accomplished. Take T0 = 298 K.
