i'm not sure help!
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.
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.
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
Alfi all
A mixture of oxygen, nitrogen, carbon dioxide and other various gases. The only reason is floats is because the hot gas inside the balloon is lifting it up.
To inflate the balloon. Whether the gas is helium or just air from your lungs, gases are needed to inflate the balloon.
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.
Because the gases filling the balloon are lighter than the surrounding air.
helium. :)
It would require adding another chemical such as baking soda to produce gases. While you could put chemicals in the balloon, you could also mix them in another container and then capture the gas released into the balloon. For instance, you could use a test tube with a stopper and a pipette.
How gases expand and contract.
Balloon.
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.
