bcoz hydrogen gas is less denser than air and is exerts buoyant force on balloon
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
Yes, hydrogen is lighter than air and so causes the balloon to float.
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium
'Hot air' balloons don't use hydrogen. They use hot air. Balloons that use hydrogen are not referred to as 'hot air' balloons. The only balloons that can accurately be referred to as 'hot air' balloons are the members of the balloon population that derive their lift/buoyancy from the presence of hot air. Of course, if a balloon used no hot air, then it could freely be referred to as a 'hydrogen' balloon, a 'helium' balloon, a 'water' balloon, etc., depending in congruent harmony with the nature of whatever substance had been chosen with which to inflate it it in order to maintain its fulsome shape.
Hydrogen is less dense than air, ergo it floats. Air is of the same density as air, but the rubber skin around it makes it more dense, ergo it sinks.
Its filled with gas because certain gases(Helium, Hydrogen) are lighter than air so they float. That's why the balloon floats.

no it will not. because a balloon filled with hydrogen floats only because it is lighter than air so when there is a vacuum it will not float. it is like oil and water if there is no water oil is on the bottom if there is water it is on the top.
Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
Helium is less dense than air
Helium is lighter than air. hence helium balloon will float in air.
because helium is a source of of air but not exactly air because it has the compounds to push against air to fly up unlike ex. if i filled a balloon with air and one with helium the one with air can floats but goes back down but the on helium floats off because its atoms in the balloon are jumping around and it has sub atomic cells
The gas in the balloon is lighter than air. It has a specific gravity relative to air of less tha one.
beecause hydrogen is less dense and light then air , easy to fly..the hydrogen in the balloon is lighter than the air outside of it.density of hydrogen is lower than air
A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it.
Sometimes it's not obvious, but gases have weight. The weight of all the air above you is called the barometric pressure. Each gas has a different weight. Hydrogen is the lightest gas so it floats on heavier gasses, just as wood floats in water. Helium is also lighter than air. That's why balloons are filled with helium, so they float in the air.
