gas yes boy
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
helium gas
Yes.
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.
Yes.... See Hindenburg.
Hydrogen can make a balloon float. Nitrogen, argon, and chlorine will not. However, hydrogen is combustible and in a balloon that cam near an ignition source, could produce a fire or explosion. The preferred gas for balloons, if cost is not an issue, is helium, which does not burn and is still very light.
Helium gas is lighter than air and hence balloons filled with helium will float in air.
Helium gas is commonly used to make balloons float because it is lighter than air and creates lift. The helium gas in the balloon is less dense than the surrounding air, causing the balloon to rise.
A balloon does not float with your breath because the air you blow into it is denser than the surrounding air. To make a balloon float, you need to use a lighter gas, such as helium, which is less dense than the surrounding air and creates enough lift to keep the balloon suspended.
Usually helium, the lightest noble gas. You can make a balloon or bag float with hydrogen gas, but it is flammable. Pure nitrogen is only slightly lighter than air, so it would not lift very effectively.
Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.
