Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
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.
A balloon filled with hydrogen gas floats in air because hydrogen is lighter than air. The buoyant force acting on the balloon is greater than the gravitational force pulling it down, allowing it to float.
Hydrogen tanks are used in balloons to provide the gas needed for lifting and floating. The hydrogen gas is lighter than air, so when it is pumped into the balloon, it creates buoyancy that allows the balloon to rise and float in the sky. The tanks are securely attached to the balloon and release the hydrogen gas as needed to maintain the desired altitude.
'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.
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 in air will rise due to the fact that hydrogen gas is less dense than air. The balloon will continue to rise until it reaches an altitude where the density of the surrounding air matches its own density. If ignited, the hydrogen in the balloon can react with oxygen in the air and create a fire or explosion.
Hydrogen is less dense than air, so it creates a buoyant force that causes the balloon to rise. This is because the density of the hydrogen inside the balloon is lower than the surrounding air, making it lighter and causing it to float upwards.
To make a balloon rise in the air, one way is to fill it with a lighter-than-air gas, such as helium or hydrogen. The gas inside the balloon is less dense than the surrounding air, enabling it to float and rise. The amount of gas and the size of the balloon will determine how high it can rise.
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
Balloons filled with hydrogen do not rise indefinitely because there is a point where the density of the surrounding air matches the density of the hydrogen in the balloon, causing the balloon to reach equilibrium and stop rising. Additionally, factors like temperature and atmospheric pressure can also affect the balloon's ability to keep rising.
with out the hot air the balloon would not rise
Hydrogen is used. Sorry. Just regular air is used in a hot air balloon, it is heated which makes it lighter and less dense and therefore provide lift. Hence the name hot air balloon. Hydrogen is used in a gas balloon.
The composition of air is roughly 78% nitrogen and the remainder except a negligable amount of hydrogen is more dense than nitrogen. Therefore a balloon filled with nitrogen will be less dense then the surrounding air and thus will rise. The balloon will probaly not rise, as there is insufficient lift to overcome the weight of the balloon fabric. Are you sure you don't mean Helium, or Hydrogen?
A balloon rises because it is filled with a gas that is lighter than the surrounding air, typically helium or hot air. The lighter gas creates buoyant force, lifting the balloon off the ground.
A hot air balloon doesn't contain helium or hydrogen.
Nearly any gas can pump up a balloon because it has mass. However, helium is used because it is lighter than air, makes balloons rise, and is fairly safe. Sure, you could put hydrogen in a balloon and it would rise, but it would be highly explosive.
Hot air balloons are typically powered by propane gas, which is a hydrocarbon made of carbon (C) and hydrogen (H) atoms. As the propane is burned, it releases heat that causes the air inside the balloon to become less dense than the surrounding cooler air, making the balloon rise.
