Would there be more air pressure in a balloon at sea level or high in the sky?

provided the balloon has not reached its elastic limit (it has burst!), the air pressure inside and outside will essentially be equal.
[The pressure inside will be slightly less, which is where the lift comes from.]
But even at altitude, the pressure will be approximately equal in and out, for at altitude, the balloon will have swelled, thus reducing the internal pressure.
It will eventually reach an altitude at which the internal pressure and the external pressure will be equal, and the balloon will have reached maximum expansion.
Filled at sea level, a balloon will seem empty and floppy, and very tall and thin. At altitude the balloon will fill out as the external pressure reduces.

Why are weather balloons partially infated before they're released into the atmosphere?
As you rise in elevation, the pressure around you decreases. This lower pressure would cause the balloon to expand, and burst if it was inflated to much originally. By starting it off only partly filled, it will expand to a normal size and not explode.
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.
Is air pressure at sea level low or high?
as we go deep into the sea, pressure would increases
What would happen if a balloon that was blown up at a low altitude is brought to a high altitude?
The ballon will most likely pop. The balloon will shrink.
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.
Why the air in the balloon increases when you are on a high altitude in aeroplane?
Actually the amount of air doesn't increase, the pressure outside the baloon decreases. When you fill a balloon at sea level, the air inside the balloon is at sea level pressure. When you climb in an airplane to 35,000 ft, the pressure outside the balloon decreases. Since the pressure is higher inside, it can push out more. This is also the same principal for when your ears pop when you climb and descend.
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.

Which of the places listed would you expect to experience the lower air pressure?
In a hot air balloon high in the sky
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.
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.

What would happen if the air outside the hot air balloon were as hot as air inside?

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.
