To inflate the balloon.
Whether the gas is helium or just air from your lungs, gases are needed to inflate the balloon.
Because the gases filling the balloon are lighter than the surrounding air.
helium. :)
Anything less dense than air (hydrogen, helium, hot air).
Balloon.
The solute in a balloon filled with air is the mixture of gases that compose air, which include nitrogen, oxygen, carbon dioxide, and other trace gases.
In a helium balloon- one that floats and rises to the ceiling it is elemental helium that is used to inflate the balloon. If you just blow into a balloon to inflate it then it is air inside the balloon which is a mixture of gases, principally nitrogen and oxygen (both elements). There are also other gases that are chemical compounds such as carbon dioxide.
To enable the gases inside the balloon to expand which they do when the balloon reaches high altitudes. At this point the balloon becomes much larger.
Gases have no definite volume or shape. The air that you breathe, the helium in a balloon, and the neon inside the tube in a neon light are gases.

9 gases in a balloon
The gases filled within the balloon escape quickly.
Because as the balloon is heated, the gases on the inside of the balloon begin to expand and press out on the walls of balloon. If a balloon is refridgerated, the opposite is true: the gases on the inside of the balloon will begin to contract, causing the balloon to shrink.
