Come atterra la mongolfiera?
Come atterra la mongolfiera?
Diminuendo la temperatura all'interno del pallone, sempre grazie all'uso del bruciatore, si può invece regolare il movimento di discesa verso il basso, che permetterà quindi l'atterraggio. Gli unici movimenti governabili con la mongolfiera sono quelli verticali, e cioè verso su e verso giù.
Why do balloons go up in the air?
- Balloons that are light enough, for example those that are filled with a type of gas that is lighter than air, like helium, have the same tendency to rise into the air, if they are not restrained. It is said that buoyancy or upward force, pulls objects like balloons up into the air.
How high do balloons go in the sky?
- How far up do balloons go into the sky? NASA’s scientific research balloons with typical volumes of 40 million cubic feet (or 1.1 million cubic meters) routinely reach altitudes of 120,000 ft (36 km), an altitude that puts them above all but about 0.5% of the atmosphere.
Is it possible to fly in a balloon?
- But it depends. Different types of balloons behave differently. I am more familiar with the large balloons flown by NASA to carry scientific instruments to very high altitudes. I have never flown in a balloon.
Why do helium balloons explode at high altitudes?
- Now the shattering effect sounds reasonable for two reasons. One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes. If you inflate a balloon beyond its limits at room temperature, it will break into small pieces up to about ten centimetres long.
