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.

When helium is add to a balloon does the molecules become larger?
No. Helium is not molecular it is a monoatomic gas.
What are the contents of a helium balloon are i what phase?
Gas
What is the helium made of in balloons?
No, a ballon cannot be made of helium, which is a gas. A ballon is made of plastic or cloth. Helium is one of the light gases that may be put into a balloon to make it lighter than air and thus able to rise in the air.
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.)
Are the contents in a helium balloon in the plasma phase?
gas
Why there are gases in the balloon?
To inflate the balloon. Whether the gas is helium or just air from your lungs, gases are needed to inflate the balloon.
When helium is add to a balloon does the molecules become larger?
No. Helium is not molecular it is a monoatomic gas.
What was the helium balloon balloon made of?
It was made out of the light gas gas Helium.
Is a helium balloon solid or gas?
Gas. Helium is a gas.
Does Target Store inflate helium balloons?
The same way everybody else inflates Helium balloons. There is a tank of pressurized Helium with a nipple fitting, the balloon if fitted over the nipple, it's opened, the gas is released, the balloon inflates, the balloon is tied off and the string attached. Voila, a balloon, for the delight of all around
Could a balloon inflate with soda gas?
Yes, but it will not inflate very much
Which gas is pumped into a balloon?
Helium gas is pumped into a balloon.
What makes a child's balloon rise?
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
If you put water yeast and sugar in a bottle and put a balloon over the top the balloon will inflate. Will it inflate if you do NOT put sugar in it If not will anything happen at all?
Yeast eats the sugar giving off CO2 which is a gas that will inflate the balloon. Added: But since carbon dioxide is heavier than air this balloon gas will never reach the 'top'
What is a gas balloon used for?
Helium
How do you compress a gas?
you have to put gas in a balloon or something for example a balloon compresses gas(helium)
What type of gas is used in balloon vendor?
Helium gas is used in a balloon vendor.
