It's easy, just stop putting hot air in it.
The current for a hot air balloon is to feel windSlide down for more
The heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down.
Yes, It is because in a hot air balloon the hot air rises and the cool air falls down.
bust the balloon
Hot air balloons go down by releasing the hot air in the balloon. Normally you just let the air inside cool and descend slowly. You release hot air only if you wish to descend more quickly.
A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.
There is a flap in the top of the balloon that you open to let the hot air out and the balloon gets lower. Or, you can just wait a little bit, the air cools down, and it goes down, all by itself!
The hot air from the fire pushes the balloon up, and putting out the fire makes it go down again :)
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.
it goes down
If the burner fails or runs out of fuel, the hot air in the balloon (that gives it lift) would cool and the balloon would come down to earth.
In rising, a hot air balloon works the same way as a helium balloon : the hot air inside is less dense than the surrounding air outside the balloon. The heavier outside air pushes below the balloon and forces it upward. To come down is easier in a hot air balloon. Unless it is continually reheated, its temperature reverts to that of the surrounding air and the balloon settles back to the Earth under its own weight. Vents that release the heated air (like venting helium in a helium balloon) is an alternative to increase the speed of descent.
