An insulated rigid tank contains 1.0 kg of air at 130 kPa and 20oC. A paddle wheel inside the tank is rotated by an external power source until the temperature in the tank rises to 54oC. If the surrounding air is at 20oC, determine (a) the energy destroyed (I) and (b) the reversible work (Wrev). Use the IG model for air. (c) What-if Scenario: What would the energy destroyed be if the initial pressure were 180 kPa instead?
