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 hydrogen in a sealed rubber party balloon is compressed slightly by the balloon rubber. So its density decreases a little, its pressure increases, and its temperature increases. But the temperature soon returns to the ambient temperature as heat is lost through the balloon wall. Also, the hydrogen will not stay in the balloon for long because it will leak out through pores in the rubber.
The hydrogen-filled balloon will deflate the fastest because hydrogen molecules are smaller and will escape through the balloon material more easily. The air-filled balloon will deflate at a moderate rate, while the carbon dioxide-filled balloon will deflate the slowest due to larger molecules that escape less easily.
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 gas can make a balloon float. This is because hydrogen is lighter than air and provides buoyancy to the balloon, causing it to rise. Nitrogen, Argon, and Chlorine are heavier than air and would not make a balloon float.
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.
in a balloon and in a hydrogen car
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.
A hot air balloon doesn't contain helium or hydrogen.
I captured hydrogen through a tube in a balloon. Then, with the balloon not all the way blown up, I put some oxygen in it. When I lit the balloon with a lighted punk it exploded with more heat and force than just a balloon with hydrogen. when the two gases were in the same balloon and not exploded they were added but not combined. When they exploded they became combined. Please, do not do this unless you have an experienced lab tech helping you.
A balloon with CO2 instead of helium or hydrogen
There is the weather balloon, and the zeppelin. Both use Helium, and no longer Hydrogen due to hydrogen's tendency to quickly catch fire.
The hydrogen in a sealed rubber party balloon is compressed slightly by the balloon rubber. So its density decreases a little, its pressure increases, and its temperature increases. But the temperature soon returns to the ambient temperature as heat is lost through the balloon wall. Also, the hydrogen will not stay in the balloon for long because it will leak out through pores in the rubber.
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
The hydrogen-filled balloon will deflate the fastest because hydrogen molecules are smaller and will escape through the balloon material more easily. The air-filled balloon will deflate at a moderate rate, while the carbon dioxide-filled balloon will deflate the slowest due to larger molecules that escape less easily.
If the balloon were lofted by hydrogen, it would not be a "hot air" balloon, as no heat would be needed. Indeed, to get even a spark near the hydrogen would be for the balloon to go up in a huge fireball. Hydrogen was abandoned as a lift gas for lighter -than-air craft in the 1930's, exactly for that reason.
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.
