An air parcel occupied by an ideal gas (T1 = 255 K, V1 = 1500m3, m1 = 1680 kg) collides and mixes with a second air parcel occupied by a second ideal gas (T2 = 280 K, V2 = 1200 m3, m2 = 1392 kg). Assuming the specific heat capacities of the gases in the two parcels are cv1 = 1.039 kJ kg-1 K-1 and cv2 = 1.005 kJ kg-1 K-1 respectively, what is: (a) the limiting temperature of the mixture, (b) the change in entropy for each parcel, (c) the change in entropy for the entire mixed system.
