Why the balloons filed with hydrogen does not rise indefinitely?

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.


How does a balloon filled with nitrogen air fly up?

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?


Why does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?

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.


What makes a balloon rise?

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.


What determines if a balloon filled with a gas will rise or sink in the air?

A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.

Which of a hydrogen filled balloon air filled balloon and a carbon dioxide filled balloon will deflate the fastest and which is the slowest and explain your answer?

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.

What happen when a balloon is filled with helium?

When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.

Why a balloon filled with hydrogen gas floats in air?

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.


What small balloon used to carry meteorological instruments into the atmosphere?

Just a met balloon - meteorological balloon. Generally filled with hydrogen.


What will happen to a hydrogen balloon when put in air?

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.


What will happen to a hydrogen balloon released on the moon?

It will fall. Wht makes a balloon rise is if what it's filled with is lighter than what's around it. But if the balloon is on the moon, what's around it is basically vacuum - nothing. And any gas is always something, and something is heavier than nothing.
