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?
Limitations of blimps, dirigibles, and hot air balloons include their susceptibility to weather conditions, limited speed and maneuverability, and dependence on wind patterns for navigation. They also have low payload capacities and are typically more expensive to operate compared to other modes of transportation.
Why can't blimps fly into space?
Blimps rely on buoyancy to stay afloat, which is achieved by being lighter than the air around them. In the vacuum of space, there is no air for the blimp to displace and generate lift, so it would not be able to remain buoyant and fly. Additionally, blimps are not designed to withstand the extreme conditions, temperatures, and lack of atmosphere in space.
What types of hot air balloons are there?
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
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.
What does helium have in it that makes it float?
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
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.
What are limitations of blimps dirigibles and hot air balloons?
Limitations of blimps, dirigibles, and hot air balloons include their susceptibility to weather conditions, limited speed and maneuverability, and dependence on wind patterns for navigation. They also have low payload capacities and are typically more expensive to operate compared to other modes of transportation.
Is helium used in hot air balloons?
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
What are the examples of air transportation?
The most obvious are being used every day. Air transportation includes: Airplanes, Helicopters, Hot Air Balloons, Blimps, Rockets, Kites, Parachutes and Birds.
How are hot air balloons blimps and dirigibles similar?
All three are types of lighter-than-air aircraft that rely on buoyancy to fly. They also have a balloon-like structure filled with a gas that is less dense than the surrounding air. However, hot air balloons specifically use heated air to generate lift, while blimps and dirigibles are powered by engines for propulsion.
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).
List several types of lighter than and heavier than air vehicles?
Heavier: Airplanes Gliders Helicopters Lighter: Blimps Balloons
