Question:

A 0.8-m3 insulated rigid tank contains 1.54 kg of carbon dioxide at 100 kPa. Now paddle wheel work is done on the system until the pressure in the tank rises to 135 kPa. Determine (a) The actual paddle-wheel work done during this process and
(b) The minimum paddle-wheel work with which this process (between the same end states) could be accomplished. Take T0 = 298 K.
