A hydrogen filled balloon of the type used in cosmic ray studies is to be expanded to its full size which is a 100-ft diameter sphere, without stress in the wall at an altitude of 150,000 ft. If the pressure and temperature at this altitude are 0.14 psia and -67 degrees F respectively,
Find the volume of hydrogen at 14.7 psia and 60 degrees F that should be added on the ground. Neglect the balloon's weight.
You can use the combined ideal gas law for this question.
[(P1)(V1)]/T1 = [(P2)(V2)]/T2
The volume of the sphere is V1=4/3 *pi*r^3 where r=radius
Thus, r ...
The answer is given step-by-step.
