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.

What has to happen for a balloon to inflate?
The pressure inside the balloon has to exceed the pressure outside the balloon.
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 happens to the pressure of the air outside of the balloon as it goes higher?
The pressure inside the balloon will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
Is the pressure of a balloon greater on the inside or outside?
It's greater on the outside until it rises to a point in the atmosphere where the air is very thing. At that point, the pressure inside the balloon is greater which causes it to pop.
Why does air rush out of a hole in a balloon?
The pressure inside is greater than outside, or else the balloon would not blown up.

How you know gas is inside the balloon?
If there were nothing inside the balloon - a vacuum - the balloon would quickly collapse due to the pressure of the atmosphere outside it. A firmer structure might resist the air pressure, but not a balloon.
Is the pressure of a balloon greater on the inside or outside?
It's greater on the outside until it rises to a point in the atmosphere where the air is very thing. At that point, the pressure inside the balloon is greater which causes it to pop.
What would change the size of a balloon?
Increased pressure on the inside, or decreased pressure on the outside.
Why does a balloon pop as it goes up to the sky?
the pressure has increased
Why does air rush out of a hole in a balloon?
The pressure inside is greater than outside, or else the balloon would not blown up.
Why does balloon become full when you blow air in it?
Once the air pressure inside the balloon is greater than the air pressure outside the surface it starts to fill. the higher the pressure inside the more the air acts against the inner rubber surface and the balloon gets harder. an empty balloon has the same air pressure inside and outside. Once you push any air in therefore you are starting to raise the air pressure inside.air molocules from you fill it up
What will change the size of the weather balloon as it rises?
The pressure of the air inside it. The higher the balloon rises, the lower the outside air-pressure. With less pressure outside, the balloon expands because of the pressure of the air inside it. Eventually, the balloon bursts, and scientists recover the instruments when they fall to earth.
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 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.
