The air in the balloon is under higher pressure than the air outside the balloon. It wants to equalize.

What could a pilot do cause the balloon back to the ground?
If a hot air balloon, then stop heating the air. If a lighter-than-air balloon then release some of the gas.
Why does a balloon shoot around the room when it is allowed to deflate?
The air escaping out of the nozzle has momentum and creates a force on the balloon. According to the laws of motion, every action has an equal and opposite reaction; the balloon pushes the air out bacwards and the air pushes the balloon forward.
When an inflated balloon is exposed to cold air?
The volume of the balloon decreases
What is a deflated balloon?
The word "deflated" means that all of the air or gas has been let out. So, a deflated balloon is one that no longer has any air in it.
What explains why a balloon bulges on one end when you pinch the other end?
The first part of the explanation is understanding why a balloon changes when you put air into it. Before you blow up a balloon, you can see that the volume is small and that the balloon is elastic. As you put more air into the balloon you are increasing the pressure. The air is packed in tight, so it attempts to push out and escape, so the balloon's surface stretches until a balance is reached. The tension of the balloon's surface combined with the outside atmosphere's pressure matches the internal pressure of the air. This equilibrium is always held. If you increase the pressure (putting more air into the balloon) the balloon's surface gives just enough so that you equilibrium is reached again. It is this maintaining of equilibrium that answers your question. If you try and decrease the volume in one area of the balloon, the air is going to push out another area of the balloon to make up for the lost volume. The volume is always maintained and the pressure remains constant.
Why does the hot air balloon come down?
Once the air cools, the balloon will lose its lift and settle back to the ground.
How is does a hot air balloon come down?
Either by releasing some of the air it contains or by not applying more heat - as the air cools the balloon descends.
When you let the air out of a balloon why do you think you feel the wind?
the breath that comes from your mouth goes into the balloon which makes that same breath. The air that you put in the balloon is the same air that will come back in your face.
How does a hot air balloon come down?
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.
Why does air come out when it is cold in the balloon and when its hot it goes back in?
It doesn't "come out" of the balloon or go "back in." The air inside the balloon is shrinking and expanding, which makes the balloon smaller when it's colder or bigger when it's warmer. This is because gases expand when heated and contracts when cooled.
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.
What is the importance of the burner in a hot air balloon?
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.
Where does the hot air balloon energy come from?
Most hot-air balloons use propane (a liquified petroleum gas) as fuel for burners which heat the air in the balloon. The heated air has lower density than the air outside the balloon, which gives it buoyancy and generates lift.
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.
When did the hot air balloon come to the us?
The hot air balloon was introduced into the United States in the late 1700s. The first flight was on January 9, 1793 in Philadelphia.
What types of matter are in a hot air balloon?
Air= air in balloon solid= balloon and basket
When you heat the air inside a hot air balloon, it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
