Does helium come out of a balloon faster than air?
Yes. The reasons are helium is monoatomicand light and therefore at a particular temperature the helium atoms move faster and can diffuse out quicker than the larger molecules N2, O2 in an air filled balloon. (This is Grahams Law of gaseous effusion in practise)Gases are diffusing through theballoon membrane in both directions- the pressure difference is not really that great after all you can inflate a balloon using only lung power.Fill a balloon with a gas such as SF6 then it will inflateas the lighter faster moving air diffuse in at a higher rate than SF6 diffuses out
What is the gas which is filled inside the balloon to make it float?
Both hydrogen and helium are gaseous elements that are not as dense as the nitrogen and oxygen in air, and can be used to fill balloons to make them lighter-than-air. Helium is the least reactive of the two, and therefore safer to use.
Could a helium balloon float all the way up into space?
NO! all gas's volume depends on temperature, as the balloon goes up, its volume decreases, resulting in it no longer floating after a certain hight, after that, it will come down and expand again, repeating this process until it losses enough air to land, or another factor interferes with it.
Why Balloon filled with helium does not raise indefinitely?
If you blow up a balloon then the helium inside it will run out after about 2 days. After those two days (maybe 3) there will be no helium left, but you will find that the balloon is still up and rounded but not as big as before. This is because the helium had got warm inside the balloon and transfered into a liguid, then that got evaporated and turned to a gas. Therefore the gas isn't helium. Because as it changed to a liquid, the liquid picked up other parts of gas and that transfered to a liquid with it to. So it is just an ordinary gas, Oxygen. Thank You. Lucie
What size helium tank will it take to fill 113 cf balloon?
a big one I know you are perhaps wanting to have fun with these helium balloons, but there is a problem - many escape into the air and eventually bust over the sea where they come down and get mistaken for food by marine animals. Marine animals can not eat rubber and this kills them. Therefore, if at all possible would you please consider using air in your balloons rather than helium.
What do you call the gas that you make when you blow in a balloon?
Helium come on man
How does a hot air balloon come down?
In rising, a hot air balloon works the same way as a helium balloon : the hot air inside is less dense than the surrounding air outside the balloon. The heavier outside air pushes below the balloon and forces it upward. To come down is easier in a hot air balloon. Unless it is continually reheated, its temperature reverts to that of the surrounding air and the balloon settles back to the Earth under its own weight. Vents that release the heated air (like venting helium in a helium balloon) is an alternative to increase the speed of descent.
What happens to gas when it is put inside a balloon?
It depends what type of gas it is. With air inside a balloon will just stay still, will be easy to lift and when you kick it like a ball it will slowly go up and then come back down again. If you have helium in a balloon, the balloon will try to go to the highest point it can get, if you go outside and let go of a balloon it rise and go far above the clouds until the balloon starts to wear out so the helium starts to slowly come out so the balloon slowly comes down.
How are scientists able to make predictions?
You assume that things that happened repeatedly in a certain way in the past will happen the same way under the same conditions in the future. If you throw a ball up in the air 500 times and it comes down 500 times, you then predict that if you throw a piano into the air it will come down as well. If you throw a helium balloon up in the air for the first time, you might predict it will also come down. When it does not, this means the theory must be rejected or changed to explain what is different this time. If you have a hydrogen balloon and throw it into the air, you might predict that since your helium balloon did not come down and hydrogen is more similar to helium than it is to a piano, then the hydrogen balloon will keep going as well.

What is a barrage balloon?
A barrage balloon is a large helium-filled balloon that is tethered to the ground with steel cables. It is used as a defensive measure to deter low-flying aircraft from attacking ground targets. The cables are intended to damage or destroy the aircraft if they come into contact with them.

Both hydrogen and helium are gaseous elements that are not as dense as the nitrogen and oxygen in air, and can be used to fill balloons to make them lighter-than-air. Helium is the least reactive of the two, and therefore safer to use.
When you fill the balloon with air and drop it will come down whereas you fill with Helium it go up why?
Normal air is made up of several different elements that occur naturally as gases. Helium is the second element on the periodic table so its lighter than every element except for hydrogen. So when you isolate helium into a balloon it wants to be at the top of all the other elements so naturally is goes up. Another example of this is how oil and water seperate in a jar. Also take density in account.

Why does the air come out of the balloon?
The air in the balloon is under higher pressure than the air outside the balloon. It wants to equalize.
