Why use heat in a hot air balloon?
Because hot air rises. And I assume because burning fuel to create the hot air is easier, perhaps a lot lighter as well, and definitely cheaper than constantly buying helium. Although blimps used that method.
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.
Why do hot air balloons rise?
Hot air is less dense than cold air, thus hot air rises in cold air. Hot air balloons trap the hot air, thus creating an upward force at the top of the balloon. With sufficient mass, the upward force upon the balloon can overcome gravity, lifting both the balloon and the burner (used to heat the air) up off the ground. To lift people you need a much larger envelope to hold the required mass of hot air to overcome the gravitational pull. The air in the balloon is heated by a burner to make it expand (become less dense). They have a lever that they pull that releases fire.The fire makes hot air and it hits the top of the hot air balloon that makes it rise. Helium-filled balloons are more commonly known as blimps (airships) which do not use burners because helium is lighter-than-air to begin with. Helium replaced hydrogen which was originally used in blimps. Using burners on hydrogen would have been foolhardy at best (refer to the Hindenburg disaster).
Why is hydrogen no longer used in air balloons?
For small balloons like individuals often have for recreational use, hot air is much easier to control than either hydrogen or helium.For the occasional blimp, or long distance balloon trip, Helium, while somewhat heavier than Hydrogen, has proven to be far safer.The Hindenburg has proven the inherent dangers of using Hydrogen Gas in blimps. While, in theory, pure hydrogen is not explosive without the presence of oxygen, any rupture in the thin material separating hydrogen from the air atmosphere can prove to be deadly.

What air do blimps use?
Blimps use lighter than air gasses namely hydrogen or helium.
What are the differences between hot air balloons and blimps?
blimps are oval shaped
Do they still use helium in blimps?
Yes they do, as helium is lighter than air and blimps will float.
Has helium ever been used in blimps?
Yes, helium has been used in blimps as a lifting gas. Helium is less dense than air, which allows it to provide buoyancy and help the blimps stay afloat. However, today, most blimps use a combination of helium for lift and air for control and propulsion.
Is lithium in blimps?
No, blimps do not contain lithium. All blimps in current service use helium
How do blimps float?
Just as a baloon does, but the only diffrence it is a much greater mass. And obviously they don't use air, they use helium which is greater then air.
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.
Why do they use helium gas in blimps?
Helium has a low density and causes balloons and blimps to float
What is the difference between blimps and airplanes?
Beside the actual design of course, the difference is that airplanes use their engines/propellers and wing to create air flow and fly while blimps, zeppelins, and the like use hot air to propel themselves up and increase or decrease hot air in the balloon to go up or down. This is the main difference between the two aircrafts.
