Question:

A 2 m3 insulated rigid tank contains 3 kg of carbon dioxide at 110 kPa. Now paddle wheel work is done on the system until the pressure in the tank rises to 127 kPa. Determine
(a) The entropy change of carbon dioxide.
(b) Work done by paddle wheel.
(c) The entropy generated in the tank and its immediate surroudings. Use the PG model.
