Helium gas is found in balloons that rise to the ceiling. This gas is less dense than air, causing the balloon to float upward.
If you want the balloons to float, you would probably use helium.
Balloons that are filled with hot air, hydrogen, or helium will float, or rise upward, because the less-dense gases inside them are displaced by the heavier air around them. Balloons will only rise until the gas density inside them is equal to the density outside. In the case of helium balloons, this may be above the elastic limit of the balloon, and it will pop or leak.
Argon is a naturally occurring element.It is not chemically reactive and is heavier than air - so your argon balloons will sit on the floor not the ceiling!
Helium gas is commonly used in balloons to make them float and rise into the sky. Helium is lighter than air and provides the lift needed to overcome gravity and allow the balloon to ascend.
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.
Generally, it is helium. Hydrogen could work, but that would be dangerous.
Balloons rise because the gas inside them is less dense than the surrounding air. When the gas molecules in the balloon are heated, they spread out, causing the balloon to become less dense and rise.

Helium is lighter than air, hence balloons filled with helium will float and rise up.
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air. This gas, typically helium or hydrogen, creates buoyancy, causing the balloon to rise and float.
Helium balloons float because helium gas is lighter than the surrounding air. This causes the balloon to be buoyant and rise up in the atmosphere.
Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
Helium is a colorless gas that is commonly used to fill balloons to make them float. It is lighter than air and non-flammable, making it safe for use in balloons.
In a "hot air" balloon, which you refer to in your question, the gas is hot air. Heated air rises, so the balloon rises. The gas used in the burner, to heat the air, is propane.
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Balloons that are filled with hot air, hydrogen, or helium will float, or rise upward, because the less-dense gases inside them are displaced by the heavier air around them.
