What would happen to an air up balloon if you take it up on a high mountain?
The balloon would get larger as the air pressure outside it dropped. At some height, the balloon would get large enough to burst.
When a balloon rises high into the air it will expand and often will burst why?
A combination of heat from the sun and the lower pressure of the surrounding air the higher you go, causes the gas in the balloon to expand. Along with the sunlight weakening the balloon material, it will burst.
What would happen if the air outside the hot air balloon were as hot as air inside?
what are the charicteristics about of a high pressure system
Why is a high altitude hot air balloon only partially filled?
As it rises, outside air pressure decreases, and the hot air inside expands and fills the balloon. Same thing is true of large helium balloons.
What does ballooning mean?
Ballooning means "ascending in a balloon", "rising high in the air, similar to a balloon", or "growing rapidly, such as a balloon".
How a pressure difference is responsible for the movement of air?
The pressure pushes it around depending on how high or low the air pressure is.ANSWERAir moves from areas of higher pressure to areas of lower pressure. If you have a water balloon and you squeeze it, the area where your fingers are is similar to a high pressure zone. The water then flows away from your fingers to the lower pressure areas of the balloon. That is how air flows in the atmosphere. Things such as humidity and temperature differences cause the different pressure zones, and the air flows from high pressure areas to lower pressure ones.
Why does the pressure outside the balloon decrease as it rises?
The pressure outside the balloon doesn't change when the balloon rises. By a balloon rising, I assume that air is being placed into the balloon. As the balloon fills with air, the pressure inside the balloon will increase. Since the balloon can stretch, the increasing pressure against its inner walls will cause it to rise, or more correctly put, expand. Eventually, the balloon will be stretched to its fullest capacity if more air is placed inside it. When it pops, the bang you hear is the high pressure of the atmosphere inside the balloon equalizing with the lower pressure of the atmosphere outside the balloon.
Where do weather balloons go?
Once the balloon gets high enough in the atmosphere, the ambient atmospheric pressure becomes very low (say 20mb = 2000Pa). There is a pressure gradient force from the high pressure of the air inside the balloon to the air in the environment outside of the balloon, working across the balloon material. Once this PGF becomes stronger than the tension of the balloon material, the balloon will pop.
Why is there air pressure in a balloon?
It is caused from unequal heating among the atmosphere. So in an area if it is heated then then the air will be less cool and denser. It is caused from unequal heating among the atmosphere. So in an area if it is heated then then the air will be less cool and denser.
Do clouds rise in the center of a low pressure or high pressure area?
Air rises in a low pressure area and sinks in a high pressure area.
What does air do in a high pressure area?
A high pressure area is usually an area that is being cooled, making the air move toward the ground. It gradually moves away from the high pressure area toward a low pressure area.
Wherever the balloon is what can you say about the pressure of the air inside and outside the balloon?
Usually, the air pressure inside a balloon is very high because the plastic outer shell of a balloon wants to contract and press the air into a small space. High in the atmosphere, air pressure is much lower than on the ground. When the air pressure outside a balloon is bigger than the air pressure inside, the balloon switches from wanting to push in on the air to the air pushing on the balloon. as this happens to some parts of a balloon and not others, it is uneven and the balloon pops.Answer:There are two distinct cases:For child's rubber balloon the air inside is at higher pressure because it is being squeezed by the rubber that wants to return to its original size. Just like you have to apply pressure to a rubber band to keep it stretched.In the case of hot air balloons the pressure on the inside of the balloon is the same as the atmospheric pressure. The balloon in this case is like an upside down bucket of air that would like to rise. It fills the container but shares the pressure of its surroundings.
Good weather is usually found in low pressure area or high pressure area?
High pressure areas
How high does a balloon rises?
It can range from the stratosphere to the mesosphere, then they will be consumed by pressure and pop
Why do most balloons burst as they ascend high altitude?
The internal pressure of the gasses inside a balloon remains constant while external air pressure decreases as the balloon ascends. As the balance between the two changes, the pressure inside becomes progressively greater than the pressure outside, so the balloon expands. If it expands beyond the ability of the balloon material to contain it, the balloon will burst.
What causes the air pressure inside an inflated balloon?
The elastic contraction of the rubber in the balloon's membrane causes the pressure in the air inside an inflated balloon. When you inflate a balloon, you have to expand the latex of the balloon, which stretches when filled with air from a pressure of 760 mm Hg to as high as 840 (about 10% higher than standard atmospheric pressure). If you inflate a non-elastic mylar balloon, it takes no effort: the air inside is at the same pressure as the air outside.
Does it move from an area of high pressure to low pressure or low pressure to high pressure?
A fluid will move from high pressure to low pressure.
