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 are scientists able to make predictions?
You assume that things that happened repeatedly in a certain way in the past will happen the same way under the same conditions in the future. If you throw a ball up in the air 500 times and it comes down 500 times, you then predict that if you throw a piano into the air it will come down as well. If you throw a helium balloon up in the air for the first time, you might predict it will also come down. When it does not, this means the theory must be rejected or changed to explain what is different this time. If you have a hydrogen balloon and throw it into the air, you might predict that since your helium balloon did not come down and hydrogen is more similar to helium than it is to a piano, then the hydrogen balloon will keep going as well.
What happens when a hot air balloon runs out of fuel?
A lack of lift with a constant weight and drag leads to rapid descent. Look for a clear landing area, jettison balast to gain time and distance and hope for the best. Ballooning is not negotiable, What Goes Up, Must Come Down.
Who kept a balloon in the air for the longest time?
Bertrand Piccard and Brian Jones when they flew around the world in 1999. They were flying a very special balloon, a combination of a helium and a hot air balloon and were aloft for 477h 47m.
How long can a balloon stay in the air when it is inflated with hot air?
I presume you mean without an airborne heater. The answer is, there is no fixed time! It could range from a few minutes to the best part of a day. It all depends on the rate the balloon loses heat, which in turn depends on the size of the balloon, the weight of the balloon, the insulation and porosity properties of the balloon fabric, and the amount of solar heating, if any, that it receives.

How does air escape from balloons?
it either has a hole in it r lettin the air out or some way over time the air goes down and no more balloon
When was Come Down in Time created?
Come Down in Time was created in 1970.
Balloon size decreasing time to time?
Balloon rubber is very thin and not completely "airtight" so gasses will leak from the balloon. This is even more apparent if the gas in the balloon is Helium or some other gas with smaller molecules than those of air.
Does helium help the balloon fly?
Yes, helium will help a balloon fly. Helium does not affect the direction that a balloon goes, but it will keep it in the air for quite some time.
What time do the balloon Pokemon come Pokemon diamond?
Every Friday. Doesn't matter what time of the day, just as long as it's Friday.
What time does the balloon guy come on Animal Crossing?
The 'balloon guy' is called Phineas. He usually come son Sundays, but can come on any random day. There is no pattern to when he comes, and he can stay for as long as he likes, usually 2 to 3 days, sometimes even up to a week.

Phineas (balloon guy) comes around anytime in AC:CF, every week. Except rainy or snowy days...
How do you come down from 2cp?

What gets smaller when time passes?
An ice cube melting, a candle burning down, and a balloon deflating are examples of things that get smaller as time passes.
What effect will the lowering of the temperature have on the gas when a balloon filled with helium was put into a freezer?
I balloon will deflate. If you take it out of the freezer, give it some time and it will expand to normal.
What time does the balloon guy come in Animal Crossing?
tuesdays around 11 am, he gives free balloons and windmills, but i think the time is different in different towns.
