A balloon having a capacity of
10000m3 is filled with helium at
20 degree Celsius and
1 atm pressure.if the balloon is loaded with
80% of mass that it can lift at ground level,at what height will the balloon come to rest?Assume that balloon`s volume is constant,the atmosphere geothermal,
20 degree Celsius,the molecular weight of air is
28.
8,and the ground level pressure is
1 atm.The mass of the balloon is
1.
