Why after 24 hours helium balloon won't fly what is happening with the helium?
The helium is escaping through the small holes of the porous balloon. Plastic does have microscopic holes in it and Helium is as small as Hydrogen gas. (Hydrogen gas is diatomic.)
Why do helium balloons shrink and stop floating?
Helium filled balloons stop floating because the helium leaks out. The balloon latex is porous and the helium is a very small atom and leaks out causing the balloon to lower and eventually stop floating.
How is possible for one tank of helium to fill 700 balloon?
Helium is stored under pressure, so a lot is packed into a small space. The gas in the balloon is at only slightly more than normal air pressure. The helium spreads out as it fills the balloons.
Why do balloons decrease in size after a while?
Why does a balloon go down after a few days?A balloon goes down after a few days because the helium can pass through the skin of a balloon which then reduces the size of the balloon and the balloon then slowly reaches the floor after loosing all its helium.If you need any more help visit www.wikipidia.comThey loose air somehow.
Why does a balloon inflate when you add helium gas?
A ballon inflates when you add helium to it for the same reason that it would inflate if you added any other gas. By Boyle's law, increasing the number of atoms of a gas to a constant space must increase the pressure of that gas. That pressure, in a balloon, must balance the force required to stretch the balloon as well as the pressure of the atmosphere pressing in on the balloon. This is not the same as the density of the displaced air. The inflated balloon would have less mass than the volume of air it displaces. This would cause the balloon to be lighter than air, and thus rise. If the elasticity of the balloon were smaller than normal, it would require more helium in a smaller volume. If the elasticity was sufficiently small, the balloon would not be lighter than air.
Which has a greater buoyant force a huge lead zepplin or a small helium filled balloon?
a small helium balloon :) i think.... i dont actually know the answer i just know that a small helium balloon will be very buoyant :)

What is an object with small mass and high capacity?
A hydrogen balloon, or for safety's sake, a helium balloon.
What will happen if you leave a balloon over night?
A small amount of air or helium within the balloon will escape through the balloon material.
How much does a small helium balloon weigh?
* Calculate the volume of the ballon * Calculate the weight of the helium: G= V x 0,1786 (the helium density in g/L) * Add the weight of the balloon material (rubber, plastic, etc.)
Why do helium balloons shrink and stop floating?
Helium filled balloons stop floating because the helium leaks out. The balloon latex is porous and the helium is a very small atom and leaks out causing the balloon to lower and eventually stop floating.
How do balloon fly?
Balloons are filled with helium. Helium is a gas that can make light objects float, or make your voice all squeaky. So if you want to pee your pants laughing, go cut a small hole in a balloon and suck the helium out and then speak.
Why can a small tank of helium gas fuel 700 balloons?
Because the particles of helium in the tank are farther apart than particles in the balloon

Elephant. :)
