What else can I help you with?
When you replace helium in a balloon with less dense hydrogen does the buoyant force on the balloon change if the balloon remains the same size?
Yes, the buoyant force on the balloon will increase when less dense hydrogen is used instead of helium. This is because hydrogen is even less dense than helium, so the overall density of the balloon-hydrogen system decreases, leading to a greater displacement of air and therefore a stronger upward buoyant force.
When you put a balloon in a cold room then in a worm room does its density change?
No. The volume of the helium will change as it expands the balloon due to the increase in temperature. The density of an element never changes. The reason for that is because density is just a fancy way of saying 'The atoms are this far apart' in the equation mass/volume = density.
A helium balloon rises in the air because it is less dense than oxygen?
A helium balloon rises in the air because helium is lighter than the surrounding air, which is mostly made up of nitrogen and oxygen. Due to the difference in density, the helium-filled balloon experiences an upward buoyant force greater than its weight, causing it to float upward.
Why does a helium filled balloon rise in relation to its density?
I'm not sure I understand the question but here goes: Helium is lighter [less dense] than air, so a helium filled balloon rises because it floats up on the more dense air.
Which has the least density between ammonia air oxygen helium and chloride?
Helium has the least density among the substances listed. It is a very light gas and is less dense than air, oxygen, ammonia, and chloride.
When you replace helium in a balloon with less dense hydrogen does the buoyant force on the balloon change if the balloon remains the same size?
Yes, the buoyant force on the balloon will increase when less dense hydrogen is used instead of helium. This is because hydrogen is even less dense than helium, so the overall density of the balloon-hydrogen system decreases, leading to a greater displacement of air and therefore a stronger upward buoyant force.
Why do helium balloons rise in air?
The helium balloon rises in air because the density of helium inside the balloon is less than that of the surrounded air that is displaced by the balloons volume. So the balloon is lighter than the surrounding air. Ice cubes float in a glass of liquid water for the same reason.
Why does a heilum balloon float and not a oxyegen balloon?
because helium has less density
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.

A helium balloon rises in the air because helium is lighter than the surrounding air, which is mostly made up of nitrogen and oxygen. Due to the difference in density, the helium-filled balloon experiences an upward buoyant force greater than its weight, causing it to float upward.
Why does helium rise and regular air sink?
A balloon filled with helium floats and a balloon filled with regular air falls to the ground because helium has less density than air so the air causes the balloon to sink because there are more molecules in it. The helium has less molecules in it so the balloon rises.
What has more density air or helium?
The density of helium is less than the density of air. You can infer this without doing any calculations by thinking about the classic example of inhaling the helium from a balloon and talking. Your voice gets squeeky high because helium is less dense than air - that is, your sound waves propagate faster through helium than through air, therefore helium is less dense.
Why does a helium balloon rise in air while ordinary balloon filled with air does not?
A helium balloon rises into the air because the density of the helium is lesser than the density of the air, therefore, the balloon rises, trying to reach above the air. Helium is lighter than air, or to be more precise, less dense. Helium gas weighs less than our atmospheric air so it floats. Same goes for hydrogen and a few other pure gases
What makes a helium balloon fly?
A balloon filled with helium flies because helium weighs less than air.
Why does a helium filled balloon rise in relation to its density?
I'm not sure I understand the question but here goes: Helium is lighter [less dense] than air, so a helium filled balloon rises because it floats up on the more dense air.
Why does gravity not pull a balloon to the ground?
A balloon filled with helium or hot air is less dense than the surrounding air, causing it to float. The buoyant force acting on the balloon is greater than the force of gravity pulling it down, allowing it to defy gravity and float upwards. This principle is known as buoyancy, based on Archimedes' principle, which states that an object will float if it is less dense than the fluid it displaces.
