Why does a hydrogen filled in balloon rise?
Hydrogen is less dense than air, so it creates a buoyant force that causes the balloon to rise. This is because the density of the hydrogen inside the balloon is lower than the surrounding air, making it lighter and causing it to float upwards.
Can you make a balloon fly without hot air or helium?
Yes, you can make a balloon fly using propellers or an electric motor to provide thrust. By attaching a propeller or motor to the balloon, you can create lift and propulsion to make it fly without the need for hot air or helium.
Why balloon fly upward?
Because of the upward force pushing it up. It is too strong to let gravity pull it down.
What type of energy does a blimp use to fly?
A blimp uses gas-filled envelopes for lift, typically helium or hydrogen. The propulsion system may be powered by gasoline engines or electric motors.
Is inside balloon solid liquid or a gas?
Inside a balloon there is gas. This gas is normally helium if you want the balloon to fly high, but hydrogen also works.
Who was the man to fly?
Pitatre De Roze was the first man to fly in the Hydrogen balloon.
What element makes space shuttles fly?
hydrogen
What are the gases used to fly balloons?
Two of the gases that are used to fly balloons are Hydrogen and Helium. Helium is the preferred gas because Hydrogen is very explosive. The Hindenburg disaster was caused by the ignition of the Hydrogen gas that filled it.
Why was hydrogen used for air balloons?
because it helps it fly in air
What allowed the hindenburgh to float and fly?
hydrogen gas which is lighter than oxygen
How do blimps fly?
They are filled with helium gas. They used to be filled with hydrogen gas but that proved to be deadly at times.
What step takes the longest in a stars life cycle?
The 'main sequence' which is also a fusion of hydrogen atoms in the atmosphere.

Which makes balloons fly up in the air carbon dioxide helium or hydrogen?
Helium is typically used to make balloons fly up in the air because it is lighter than air and creates lift. Hydrogen is also lighter than air and can be used, but it is flammable. Carbon dioxide is heavier than air and would cause a balloon to sink.
Is hydrogen useful to fly?
Yes, hydrogen is useful for flying because it is a lightweight and efficient fuel source that can power aircraft, such as hydrogen-powered airplanes or airships. It is also renewable and produces zero emissions when used as a fuel, making it a more environmentally friendly option for air travel.
What were the advantages and disadvantages of using hydrogen gas in a dirigible?
Advantages: Hydrogen gas is lighter than air, providing lift for dirigibles to fly. It is also abundant and inexpensive. Disadvantages: Hydrogen gas is highly flammable, posing a significant safety risk. This led to the famous Hindenburg disaster in 1937, highlighting the dangers of using hydrogen in dirigibles.
