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.)
Suppose you have two balloons--one filled with hydrogen and the other with chlorine at the same temperature. If both balloons have the same number of molecules, which of the following statements is true? A. The balloons have the same density. B. The balloons have the same volume. C. The average speed of the gases is the same. D. The balloon filled with hydrogen has more atoms than the balloon filled with chlorine.
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,...
A cylinder of volume 43.8 L helium is filled to a gauge pressure of 1.72 x 10^7 Pa in a cylinder. a) With that amount of helium, how many balloons can be inflated to a volume of 4.0 L and pressure of 1.01 x 10^5 Pa, assuming that the balloons and the cylinder are at the same temperature? b) If the temperature of the balloons is 77 degrees Fahrenheit, then how many moles of helium are in one balloon? c)...

two life perservers gave identical volumes, one filled wiyh styrofoam and ghe other filled wiyj sand. when both are fully submereged, the buoyant force is greater in the ine filled with what?
A new kind of balloon is designed to be a perfect cube in shape, no matter how full. Suppose of these balloons can be stretched to a maximum surface area of 1435 cm2. The balloon is filled with 2.87 L of helium gas at a pressure of 746 torr and a temperature of 298 K. The balloon is then allowed to rise in the atmosphere. If the atmospheric temperature is 260 K, at what pressure will the balloon burst? Suppose...
A spherical balloon has a radius of 7.65 m and is filled with helium. The density of helium is 0.179 kg/m3, and the density of air is 1.29 kg/m3. The skin and structure of the balloon has a mass of 930 kg . Neglect the buoyant force on the cargo volume itself. Determine the largest mass of cargo the balloon can lift.
Two balloons are filled to the same pressure at the same temperature. One is filled with 1.40 moles of nitrogen; the other is filled with 1.40 moles of carbon dioxide. How many times more dense is this gas relative to the other? Please enter 1 if the densities of the gases are equal; please enter 0 if the value cannot be determined.
