The air pressure inside the balloon will be slightly higher than outside. This is because the air inside the balloon is slightly compressed by the elasticity of the membrane of the balloon itself. By way of illustration, if you inflate a balloon, don't tie it and just let it go, then to everyones' amusement at parties the balloon flies crazily around the room until it is fully deflated! This fun aspect of balloons occurs as a result of the higher pressure inside the balloon escaping from the balloon to join the air in the room that is at normal pressure. Actually measuring the pressure inside the inflated balloon would require an experiment where the volume of pressurised air in the inflated balloon could be measured by a) measuring the volume of pressurised air inside the balloon by fully immersing the inflated balloon in a measuring receptacle full of water (with normal atmospheric pressure in the room pressing down on the surface of the water) and, then b) measuring the volume that the pressurised airinside the balloon would occupy once outside the balloon at normal atmospheric air pressure by inverting the measuring receptacle full of water (whilst held in a larger shallow tank of water so as to keep the measuring receptacle full of water once inverted - in the usual physics lab manner) and then release the air from the balloon into inverted water-filled measuring receptacle where it would gather in the top of the same. The difference in the two volumes would directly correlate with the difference in air pressure inside and outside the balloon.

Why does a balloon pop as it goes up to the sky?
the pressure has increased
What explains why a balloon bulges on one end when you pinch the other end?
The first part of the explanation is understanding why a balloon changes when you put air into it. Before you blow up a balloon, you can see that the volume is small and that the balloon is elastic. As you put more air into the balloon you are increasing the pressure. The air is packed in tight, so it attempts to push out and escape, so the balloon's surface stretches until a balance is reached. The tension of the balloon's surface combined with the outside atmosphere's pressure matches the internal pressure of the air. This equilibrium is always held. If you increase the pressure (putting more air into the balloon) the balloon's surface gives just enough so that you equilibrium is reached again. It is this maintaining of equilibrium that answers your question. If you try and decrease the volume in one area of the balloon, the air is going to push out another area of the balloon to make up for the lost volume. The volume is always maintained and the pressure remains constant.
A blown up balloon is carried up a high mountain will it get bigger or smaller explain why its volume changes?
As balloons increase in altitude, there is less atmospheric pressure pushing on it, so the result is that the balloon expands. The opposite is true, if you sink a balloon in water there is more pressure on the outside of the balloon so it shrinks.
What do air particles do to keep a balloon inflated?
It's buoyancy - the same as a ship floating in water.In this case the volume of the balloon must weigh less than an equal volume of air.(That's done by using a lighter than air gas - hydrogen, helium, or just heated air.)
Can you use helium in an air balloon not hot air just ordinary party balloons?
yes, but when using Helium you must have the balloon completely sealed and used a mylar material for the balloon as Helium 'leaks-out' of ordinary materials.
Will air escape faster from a water balloon or a party balloon?
Below, the term "air molecules" refers to any molecules present in air; it is not meant to imply air is a homogeneous fluid.Assuming that both balloons are made of the same material, the water balloon will keep air in it the longest. This is for two main reasons:the balloon stretches more in a normally filled party balloon than in a normally filled water balloon. This implies that the internal pressure of the party balloon is greater, meaning more the air molecules inside the balloon will collide with the inside of the balloon more frequently than if the pressure was lower.the party balloon has a higher surface area to volume ratio. This means that air molecules are more likely to collide against the side of the balloon, compared to collisions other air molecules.Both of these factors would cause a party balloon to lose air faster than a water balloon.
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.
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 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 does the air in a balloon pass through the balloon into the surrounding air when it goes flat?
Pressure. You are describing a blow-up balloon, not a hot-air balloon. In a blow-up balloon, you put a lot of air in it and it is under pressure. It is under more pressure than the air around it. That means the air inside is pushing to get out. Actually, to be technical, the air on both sides is happy to go to the other side, if possible, but the pressure causes more air to leave than comes in. Once the air starts to leave, the pressure goes down and the balloon deflates. Once the pressure is the same inside and out, it will look flat.
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.
How can you determine the mass volume and density of a textbook a container of milk and an air balloon?
You need to measure the mass using appropriate equipment. You can measure the volume of a textbook and a container of milk by measuring its linear dimensions and calculating the volume. It is not at all easy to measure the volume of an air balloon. You cannot use displacement of a fluid (water) because when submerged, the balloon would be experiencing water pressure and so would occupy a smaller volume. You cannot measure it by allowing the air to escape and measure that volume of air because that air will no longer be experiencing the pressure exerted by the material (rubber?) of the balloon. I have no answer to this part. Once you have the mass and volume, the density is merely mass/volume.
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.
What happens to a balloon if you keep blowing air into it?
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
What makes a balloon rise on air?
A balloon rises on the principle of buoyancy. This occurs when the net pressure on the bottom of the balloon exceeds the net pressure on top of the balloon.
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
Why will a hot air balloon rise and then float at a certain height in air?
increasing altitude decreases air pressure, this pressure gradient with gravity decides if things sink or float. heating the air in the balloon decreases the weight of the balloon and allows the downward pressure from above plus the weight of the balloon to be less than the upward air pressure from below. hence the balloon rises due to this force imbalance. the balloon reaches a constant height when all three are equal
