An inflatable balloon is attached to a rigid tank. The air in the inflatable balloon is initially at 100 kPa gauge and 3 m3 while the rigid tank has a volume of 10 m3 and the air there is contained a measured pressure of 450 kPa. Open the valve between the two circles and the volume of the ball is directly proportional to its absolute pressure during its evolution. What will be the volume of the balloon after you open the valve if the surrounding environment is 100 kPa and the air temperature is kept constant at 27 oC.
