m 5. (11 marks total) A well-insulated rigid container is subdivided by a partition into two parts A and B, each of volume V = V = 0.2 m³, and each filled with air. The initial temperatures and pressures are P₁ = 200 kPa, T₁ = 100°C, P = 100 kPa, and T, = 20°C. The partition is then removed, and the system comes to equilibrium. (a) (7 marks) Determine the final temperature and pressure in the container. (b) (4 marks) Calculate the total entropy change for the air in the container in kJ/K. You may assume that air is a perfect gas with constant specific heats. A
