That would be the Hindenburg if I'm not mistaken.
Because of an accident that happened. A weather balloon was filled with hydrogen and when lightning hit it, it set on fire. Hydrogen is flammable, so they use Helium instead, because Helium is a nobel gas and so isn't flammable, but also lighter than air so the balloon floats.
Hydrogen is used in weather balloons because they are very light which help the balloon to float or fly easily.
hot air balloon
'Helium' because it is also an INERT (Noble) gas. Hydrogen could be used to make the balloon float/rise, but hydrogen is a flammable gas. On explosion you will have a flash of flame.
The radiosonde is attached helium or hydrogen- filled balloon, generally called a weather balloon, and the balloon lifts the radiosonde to altitudes exceeding 115,000 feet. During the radiosonde's ascent, it transmits data on temperature, pressure, and humidity to a sea-, air-, or land-based receiving station (According to google that is) XD ;)
Hydrogen.
I captured hydrogen through a tube in a balloon. Then, with the balloon not all the way blown up, I put some oxygen in it. When I lit the balloon with a lighted punk it exploded with more heat and force than just a balloon with hydrogen. when the two gases were in the same balloon and not exploded they were added but not combined. When they exploded they became combined. Please, do not do this unless you have an experienced lab tech helping you.
A balloon filled with hydrogen can explode.
It was a dirigible- a lighter-than-air airship with a rigid frame. It was lighter than air since it was filled with hydrogen gas. Unfortunately hydrogen is also extremely flammable.
They could be, but generally are not. Hydrogen can be an explosive gas in our atmosphere, and a spark could cause the balloon to ignite and explode. In 1937, the airship Hindenberg, which was filled with hydrogen, did so. Children's party balloons are generally filled with helium.
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
1937
the Hindenburg is an airship that exploded inMay 6, 1937
in a balloon and in a hydrogen car
A hot air balloon doesn't contain helium or hydrogen.
R101 was filled with hydrogen.
A balloon with CO2 instead of helium or hydrogen
