Question: Consider a balloon which is initially empty. Now, it is filled with helium by means of a balloon pump which provides helium at 1 2

Consider a balloon which is initially empty. Now, it is filled with helium by means of a balloon pump
which provides helium at 125kPa and 300K. A pressure measurement device is connected to the
balloon to measure the pressure in the balloon and it is observed that when pressure is 112kPa, the
volume is 0.1m3. The process ends when the pressure and the temperature of helium in the balloon are
124kPa and 310K, respectively. If the final volume in the balloon is 0.2m3, find the amount of heat
transferred during this process and the amount of entropy generated. Assume that
Helium is an ideal gas with constant specific heats.
Pressure varies linearly with volume.
Ambient temperature is 290K.
