How do hot air balloons descend?
Hot air balloons descend by releasing hot air from the balloon envelope, causing it to cool down and become denser. This decrease in density causes the balloon to descend slowly until it reaches the ground. Pilots control the rate of descent by manipulating the amount of heat in the balloon.
What gas is used for a hot airballoon?
I am fairly sure that hot air balloons use normal air. They rely more on the idea of bouyancy rather than using specal gases, such as helium. The hot air inside of the balloon is more bouyant than the cold air outside of the balloon. So that makes the balloon ascend till the temperature of the air inside of the balloon is equal to the temperature of the air outside of the balloon. Then as the air inside the balloon gets colder, the balloon starts to descend.
What elements are used in an air balloon?
Hot air is common.
What happens to a balloon on a hot day and what might happen if it gets to hot?
On a hot day, the air molecules inside the balloon gain energy and move faster, causing them to expand and the balloon to inflate. If a balloon gets too hot, the increased pressure from the expanding air can cause it to burst.
Why does a hot air balloon float?
A hot air balloon floats because the hot air inside the balloon is less dense than the cooler air outside. This temperature difference creates buoyancy, causing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can control the altitude of the balloon.
