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.
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 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 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 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.
If you are comparing two balloons side by side, a hydrogen balloon will have more lift than a helium balloon of the same size and construction.If you open the balloons, the hydrogen is flammable, while the helium is not.

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.
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.
Baloon filled with hydrogen gas float in air or rises if the quntity of gas it contain is adjusted so that the average density of the balloon is just eguall to the density of the surrounding air.The weight of the displaces air is then eguall to the weight of the balloon
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
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.
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.
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.
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.
