An insulated 5000 Liter rigid tank contains air at 5 bar and 330 K. A valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 2 bar. The air temperature during this process is maintained constant by an electric resistance heater placed in the tank. 111 SA valve insalated Tak 1114 Air, V-5000 Liter Res bar T₁-T330k P= 2 bar We Below 30 O Between 30 and 31 Between 31 and 32 Between 32 and 33 Above 33 O the final mass of air in the tank in ( :kg) is Below 6 Between 6 and 8 Between 8 and 10 *3 * the electrical energy supplied to heater :in (kJ) is Between 10 and 12 O Above 12 O Below 1200 O Between 1200 and 1400 Between 1400 and 1600 Between 1600 and 1800 Above 1800 * :the total entropy change in (kJ/k) is Below 1 Between 1 and 3 O Between 3 and 5 Between 5 and 7 O Above 7 OE
