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.
Helium gas is less dense than air, so it will rise and float in both air and water.
Farts rise in the air because they are lighter than the surrounding air.
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
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.
Helium. It is lighter than air and provides buoyancy, causing the balloon to rise.
Helium is lighter than air. So it will float in air.
Helium gas is less dense than air, so it will rise and float in both air and water.
If it is cooled its gets extremely cold from the helium,and when the heat is in the balloon it keeps it warm when its in the helium
If the house is filled with regular air - yes. If it isn't, it'll depend on what gasses there is in the house.
because helium is ligter than air
Helium is lighter than air. So helium balloon rises in air.
yes honey, that's why hot air balloons rise
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain
You can use air instead of helium, but it will not rise. The reason helium balloons rise is because helium is lighter than air. I am sure other gases can be used also.
Helium rises because it is less dense than the surrounding air. On the other hand, carbon dioxide sinks because it is more dense than the surrounding air. This difference in density causes helium to float upward and carbon dioxide to sink downward.
Farts rise in the air because they are lighter than the surrounding air.
A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it.
