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.
A hydrogen balloon rises in air because the hydrogen gas inside the balloon is lighter than the surrounding air. This makes it buoyant, causing it to float upwards. The difference in density between the hydrogen gas and the air creates an upward force, lifting the balloon off the ground.
The explosion of a balloon filled with hydrogen gas upon contact with a spark is a chemical change. This is because the hydrogen gas (H₂) reacts with oxygen (O₂) in the air to form water (H₂O) and release energy in the form of an explosion.
Weather balloons are traditionally filled with hydrogen due to its low density and cost-effectiveness. However, helium is a safer alternative because it is non-flammable. The choice between hydrogen and helium depends on safety considerations and budget constraints.
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.
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
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.
An air balloon or a feather can be used to represent air. The balloon is filled with air and floats, while the feather is light and gets easily carried by the air.
A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it.
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.
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
