3. [25 pts] As shown in Figure P3, a 1.5 m³ insulated rigid tank contains 2 kg of air at 100 kPa. Now paddle-wheel work is done on the system until the pressure in the tank rises to 150 kPa. Determine 1) the entropy change of air (AS) in kJ/K during this process, and 2) the entropy generation of air (0) in kJ/K during this process. 3) Discuss if the process satisfies the 2nd law of thermodynamics.
