Will a hot air balloon fly better on high pressure or low pressure?

High pressure.
A hot air balloon has a maximum altitude, where it has only just enough lift to keep it there, because there is very little difference in density between hot (near) vacuum and cold (near) vacuum.

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.
When is a hot air balloon behaving like an air mass in a high pressure area?
When the air mass is like the hot-air balloon =P
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.
Why it is easy to remove air from balloon than from bottle?
This is because the air inside the balloon is a fairly high pressure than the atmospheric pressure air outside the balloon. On the other hand air pressure inside the glass bottle is already equal to the atmospheric pressure so it is difficult to remove air from a glass bottle.
How does a balloon expand?
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
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.
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
How high will you go with a hot air balloon tour?
While a hot air balloon can fly several miles in the air, a tour balloon will generally only go about a mile up due to pressure concerns.
Which of the places listed would you expect to experience the lower air pressure?
In a hot air balloon high in the sky
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.
How does Bernoulli's principle relate to the hot air balloon?
this happens because the high pressure wants to go to low pressure
