- A balloon is filled with helium gas. When each of the following changes are made at constant temperature, which of these diagrams (A, B, or C) shows the final volume of the balloon?

- Nov 06, 2006 A balloon filled with helium gas at 20 degrees C occupies 2.91 L at 1.00 atm. The balloon is immersed in liquid nitrogen at -196 degrees C that applies an external pressure of 5.20 atm to it.
We’ve all let go of a latex helium balloon, whether intentionally or by accident, but what happens once that helium balloon soars out of our vision?
Why does a helium balloon float?
A wide variety of helium gas filled balloon options are available to you, such as high, low. You can also choose from latex, steel, and foil helium gas filled balloon, as well as from gift toy, promotional toy, and advertising toy helium gas filled balloon, and whether helium gas filled balloon is unisex.

A filled helium balloon rises because of the simple fact that helium is lighter than air.
What happens to the helium balloon as it rises?
As altitude increases, the density of the atmosphere decreases. So as a latex helium balloon rises, the outside air pressure diminishes, while the pressure from inside of the balloon remains the same. This causes the elastic material of the latex helium balloon to expand.
As the latex expands, the helium balloon increases in volume, thereby increasing its buoyancy. The more a balloon’s material can safely expand, the higher it will rise. free. software download site for mac.

A Balloon Filled With Helium Gas
How high can a helium balloon go?
This depends largely on the material of the helium balloon. One made of a stronger latex will be able to expand (and ascend) more than one that is made of a weaker latex.
In a 1992 study of a test of toy balloons for the Federal Department of Aviation, researchers found that latex helium balloons can rise to an altitude of 5.7 miles to 6.6 miles before popping.
What happens when the helium balloon pops?
Inflate a helium balloon indoors until it pops and you’ll be left with relatively large pieces of rubber. Do it 5 miles up in the air and something quite different happens.
When a latex helium balloon reaches the low temperatures within that 5-6 mile altitude range, it will actually freeze. The elasticity of latex decreases significantly in low temperatures, so the helium balloon that was expanding suddenly becomes incredibly brittle.

What happens next is not the traditional pop that you and I are used to seeing, but instead something simply called “shattering.” The helium balloon breaks in a manner that is similar to smashing a mirror, and all that is left are very small pieces of cold latex that sprinkle back down to the planet.
(It’s said that these shattered pieces are too small to pose any threats to animals because they are easily passed through the system if ingested.)
Variables
Of course, there are exceptions. Variables that can throw a hitch in these rules include poorly manufactured or flawed latex, latex that is unable to expand significantly or expands too quickly, helium balloons that are not fully inflated, or the altitude and climate of the place from which the balloon was released.
What about a foil helium balloon?
Due to their shattering capability, professionals will only use 100% biodegradable latex balloons during intentional releases so that large pieces of material are not left littering the ground or water.

But accidental or unprofessional releases of other balloons like foil do happen.
In the same 1992 study referenced earlier, mylar balloons rose only to about 3,280 feet, with some reaching a maximum of 1.5 miles, where they would eventually either burst open or simply “lose their lift” and glide back down to Earth.
