A Balloon is to be filled from a helium tank. The tank is large and the tank pressure remains effectively constant while the balloon is filled. A valve between the tank and the balloon controls the helium flow to a constant rate of 0.05kg/s. The pressure in the balloon varies during the filling process. The temperature of the helium entering the balloon is 20'C

1) How much work is done in filling the balloon to a final pressure of 500kPa, where the final radius is 2m if the balloon is adiabatic (it takes 8min to fill the balloon)

2) What is the final Temperature in the balloon?
