A weather balloon is filled with helium at ground level. The volume of the helium is 4.0 m3 and its pressure is 100 kPa. The balloon rises. At a height of 5000 m the pressure of the helium has fallen to 50 kPa. The temperature of the helium does not change.
Calculate the volume of the helium at a height of 5000 m.
Determine the increase in the volume of the helium as the balloon rises to a height of 5000 m.
The balloon bursts when the volume of the helium reaches 12 m3. Determine the pressure of the helium at the moment the balloon bursts.
