Bertrand Piccard and Brian Jones when they flew around the world in 1999. They were flying a very special balloon, a combination of a helium and a hot air balloon and were aloft for 477h 47m.

How long did the hot air balloon float in the air?
The longest someone has flown in the air is 50 hours!
Why are hot air balloons not shaped as air planes?
Because air planes are kept in the air by the way air flows around and against their surfaces while a balloon is kept in the air by the air inside the balloon is lighter than the air outside it. Basically a balloon is floating in air. And a roundish shape is what allows the biggest volume inside for the least amount of surface area, meaning that you get the most lift from the least amount of cloth.
Does energy from burning of gas in a hot air balloon transfer to the air around it?
The air inside a hot air balloon is heated by burning fuel (usually propane). The air is kept inside the balloon so it doesn't readily mix with the cold air outside the balloon, but there is of course energy transfer from the hot air to the fabric and then to the surrounding colder air. This is why a balloon needs to fire the burner periodically, to reheat the air that has cooled or been lost through venting (to cause the balloon to rotate or fly lower)
Why air balloon come down after some time?
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
How does hot and cold air have an effect on an balloon?
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.

Is there a world record for longest standing balloon?
As of my last update, the longest time a balloon has been stood on is 17 hours, 21 minutes, and 15 seconds. This record was achieved by Anthony Trahair of the UK in 1998.
What time fly hot air balloon?
i think it takes a long time for a hot air balloon to fly

Does air resistance keep a hot air balloon in the air?
No, hot air balloons are kept up in the air by buoyancy, the same thing that keeps helium balloons up in the air, or that keeps ships afloat. The hot air in the balloon is less dense than the surrounding air, so the balloon weighs less than the air it displaces, at least while the balloon is rising.
Why does balloon burst when it is kept in sun?
Heat causes substances to expand. When left in the sun the air inside the beach ball will expand. If the air expands enough it will burst the beach ball.

What is the longest hot air balloon flight?
On January 15, 1991, the Virgin Pacific Flyer balloon completed the longest flight in a hot air balloon when Per Lindstrand (born in Sweden, but resident in the UK) and Richard Branson of the UK flew 7,671.91 km (4,767.10 mi) from Japan to Northern Canada.
What time did the hot air balloon was made?
In 1783
Will air escape faster from a water balloon or a party balloon?
Below, the term "air molecules" refers to any molecules present in air; it is not meant to imply air is a homogeneous fluid.Assuming that both balloons are made of the same material, the water balloon will keep air in it the longest. This is for two main reasons:the balloon stretches more in a normally filled party balloon than in a normally filled water balloon. This implies that the internal pressure of the party balloon is greater, meaning more the air molecules inside the balloon will collide with the inside of the balloon more frequently than if the pressure was lower.the party balloon has a higher surface area to volume ratio. This means that air molecules are more likely to collide against the side of the balloon, compared to collisions other air molecules.Both of these factors would cause a party balloon to lose air faster than a water balloon.
Why doesn't the hot air escape out of the bottom of a hot air balloon?
Because hot air rises, the warmest air in the balloon is at the top of it. As time passes the balloonist has to fire the burners to maintain the temperature of the air in the balloon, and to prevent it being squeezed put by the higher pressure of the cold air surrounding the balloon.
Why air balloon come down after some time?
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
