If the balloon were lofted by hydrogen, it would not be a "hot air" balloon, as no heat would be needed. Indeed, to get even a spark near the hydrogen would be for the balloon to go up in a huge fireball. Hydrogen was abandoned as a lift gas for lighter -than-air craft in the 1930's, exactly for that reason.
A hot air balloon doesn't contain helium or hydrogen.
Hydrogen is used. Sorry. Just regular air is used in a hot air balloon, it is heated which makes it lighter and less dense and therefore provide lift. Hence the name hot air balloon. Hydrogen is used in a gas balloon.
No, a blimp is not a type of hot air balloon. While both are inflated with gas to become buoyant, hot air balloons rely on heated air to rise, while blimps are powered by engines and filled with helium or hydrogen gas for lift.
no, it is powered by heat. heat rises.
no, it is powered by heat. heat rises.
A candle-powered hot air balloon works by heating the air inside the balloon with a suspended candle flame. As the air inside the balloon is heated, it becomes less dense and rises, creating lift. The balloon will continue to rise until the air inside cools down or the flame is extinguished.
'Hot air' balloons don't use hydrogen. They use hot air. Balloons that use hydrogen are not referred to as 'hot air' balloons. The only balloons that can accurately be referred to as 'hot air' balloons are the members of the balloon population that derive their lift/buoyancy from the presence of hot air. Of course, if a balloon used no hot air, then it could freely be referred to as a 'hydrogen' balloon, a 'helium' balloon, a 'water' balloon, etc., depending in congruent harmony with the nature of whatever substance had been chosen with which to inflate it it in order to maintain its fulsome shape.
A hot air balloon is powered by heated air, which is less dense than the cooler air outside the balloon. The heat is generated by a burner that typically uses propane as fuel. As the air inside the envelope is heated, it causes the balloon to rise, while lowering the temperature allows it to descend. The pilot controls the altitude by managing the heat and the release of hot air.
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
hydrogen
Anything less dense than air (hydrogen, helium, hot air).
