Describe conceptually how high up a balloon filled with Helium gas can lift, given that the balloon itself can expand to a certain extent. Can the balloon disappear into space?
Homework Answers
Air mostly contains heavier molecules of Oxygen and Nitrogen gas.Due to decrease in gravitational force with height, density of air decreases with incresing height.
A balloon filled with Helium gas which has light molecules starts rising up due to buoyant force exerted by the air. The balloon keeps on rising till the certain height where there is very less density of air which let the Helium gas inside to expand. Due to the expansion, the balloon will burst out, and it will vanish in the space. Normaly the balloon rises upto the height of 9km.
If the material of the balloon is too much strong that it will not burst on the expansion of the Helium gas, at that case the balloon will rise up the height till its weight is balanced by the buoyant force exerted by the air.

A spherical balloon of 11 m in diameter is filled with helium of gas constant, R = 2.0771 kJ/kg.K at T = 15 oC and P = 100 kPa. If the balloon is used to lift load in the air of 1.25 kg/m3 density, how much load in Newtons (in addition to its own weight) can the balloon carry. Ignore drag force and weight of the balloon’s fabric? (Volume of a sphere = 4 3 ??^3 ).

Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...
