Two identical balloons are filled to the same volume, one with air and one with helium. The next day, the volume of the air-filled balloon has decreased by 5.1 % .
By what percent has the volume of the helium-filled balloon decreased? (Assume that the air is four-fifths nitrogen and one-fifth oxygen, and that the temperature did not change.)

Balloons are often filled with helium gas because it weighs only about one seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb Pairg Vballoon. will push the balloon upward. The balloon has a diameter of 9 m Assume the density of air is ρ 116 kg/m3 and the density of helium gas to be 1/7th of this Neglect the weight of the ropes and the cage. Determine the maximum amount of Joad,...

Large helium-filled balloons are used to lift scientific equipment to high altitudes. What is the pressure, in atmospheres, inside such a balloon if it starts out at sea level with a pressure of one atmosphere and a temperature of 10.0 degree C and rises to an altitude where its volume is twenty times the original volume and its temperature is -48DegreeC ? What is the gauge pressure, in atmospheres, in the balloon then? (Assume the atmospheric pressure is constant.)
