How long did the hot air balloon float in the air?
The longest someone has flown in the air is 50 hours!
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.
What supplies do you need to break the world record of keeping a balloon in the air the longest?
To break the world record for keeping a balloon in the air the longest, you will need a high-quality helium balloon to ensure it stays buoyant, a lightweight and durable string to control its movement, and a reliable air pump for quick inflation. Additionally, having a comfortable space with minimal distractions and potential obstacles is crucial for maintaining focus during the attempt. A timer or stopwatch to track the duration is also essential.
Why does an inflated balloon kept under the sun burst after some time?
The heat from the sun causes the air molecules inside the balloon to expand, increasing the pressure within the balloon. If the pressure becomes too high, the balloon will burst to release the excess pressure.
Is there a world record for longest standing balloon?
Probably, they have world record for everything else!
What time fly hot air balloon?
i think it takes a long time for a hot air balloon to fly
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.
How long did the hot air balloon float in the air?

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.
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.
What is the relationship between time and balloon size?
As time passes, a balloon will gradually deflate due to the air molecules inside the balloon escaping through the balloon material. This will result in a reduction in the size of the balloon over time.

What time did the hot air balloon was made?
In 1783
Why an inflated balloon is burst when kept in the freezer?
When a balloon is placed in the freezer, the air inside it contracts and decreases in volume due to the cold temperatures. The rubber of the balloon becomes less flexible in the cold, making it so the balloon can't stretch to accommodate the reduced air volume inside. This increase in pressure causes the balloon to burst.
