Balloons float because of the same principal as how ships float: bouyancy. A ship displaces a volume of water. If the ship's weight is less than the volume of water that it displaces, then it will float. Same is true for a balloon. It displaces a volume of air. If the Hydrogen or Helium in the balloon weighs less than the volume of air it displaces, then it will rise.

What are limitations of blimps dirigibles and hot air balloons?

How can blimps be use in scientific studies of the air?

How far can hot air balloons go?
It depends on the speed of the wind, the size of the balloon, and the amount of fuel carried. Hot air balloons have flown across the Atlantic and the Pacific oceans. However a typical flight will last about an hour and travel maybe 10 miles.

What is the gas used in hot air balloon?
Air - a mixture of nitrogen, oxygen, carbon dioxide and other gases. When heated, air becomes less dense and so it will float in cooler (= more dense) air, giving the balloon its lift.Airships and blimps are different to hot air balloons in that they gain lift from an envelope (the balloon) filled with a gas that is lighter than air. In the past, this was hydrogen but use of this gas was stopped due to its extremely flammable nature and helium is now used instead.Used gasses in balloons: helium, hot air, hydrogen.
What are the differences between hot air balloons and blimps?
blimps are oval shaped
What is helium mostly found in?
In helium balloons and blimps. Helium is lighter than air. So balloons or blimps filled with helium will float or rise up

What makes helium great to use in balloons and blimps?
Helium's density is less than the density of air, so it floats in air.
How are hot air balloons blimps and dirigibles similar?
um dont ask me omg man
What does helium have in it that makes it float?
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
What objects contain helium?
Helium is generally used in helium balloons and blimps. Helium is lighter than air and these items will float in air
How does helium help flight?
Helium is lighter than air. So balloons or blimps filled with helium will rise up and float.
What are the examples of air?
The most obvious are being used every day. Air transportation includes: Airplanes, Helicopters, Hot Air Balloons, Blimps, Rockets, Kites, Parachutes and Birds.

List several types of lighter than and heavier than air vehicles?
Heavier: Airplanes Gliders Helicopters Lighter: Blimps Balloons
How many type aircraft?
There are "lighter-than-air" craft which are known as blimps or balloons, "heavier-than-air" craft which are divided into fixed-wing (airplanes) and rotary wings (helicopters).
