Why does a balloon filled with helium gas rises up in the air?
helium is lighter that air so rises above the air. similar to oil rising above water.
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.
Why does a hot air balloon float even though it is so heavy?
Relatively hot air balloon are pretty light, and they have a very large balloon which is filled with hot air, which naturally rises, and if you contain enough of it it is enough to lift the balloon.
Why do balloons rise in the air?
A balloon rises in the air only if the balloon has a lower mass than an equal volume of the air surrounding it.That might be the case if the balloon were filled with a light gas such as helium, for example. The balloon rises because the pressure of the air around it pushes it up in the same way that water causes an air bubble to rise.
Why are Hot air balloons are filled with air instead of helium?
They are not! The air inside them is trapped in the balloon and heated, expands, becomes less dense and rises therefore pulling the balloon up with it. If helium was used it would explode! :)
Why does a hot air balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
Why does a hot balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
When does a hot air balloon rise?
When a hot air balloon is filled with the hot air the air around the balloon is a lot denser. So by convection the balloon rises and the less dense air is replaced by dense air underneath it.

What happens to the balloon as it rises?
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

What is the name of the gas that is filled in hot air balloons to make them soar and rise up in the sky?
In a "hot air" balloon, which you refer to in your question, the gas is hot air. Heated air rises, so the balloon rises. The gas used in the burner, to heat the air, is propane.
A deflated hot-air balloon weighs a total of 8000 n filled with hot air the balloon rises to a height of 1000 m how much work is accomplished by the hot air?
8J
Gas that is less dense than air?
Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
As a helium filled balloon rises in the air it becomes?
Larger (the air pressure is dropping as it rises).
