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.
the pressure has increased
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.
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.
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.)
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.
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.
The pressure inside a balloon is determined by factors such as the amount of air or gas in the balloon, the volume of the balloon, and the temperature of the air or gas inside. As more air or gas is added to the balloon, the pressure will increase. Conversely, if air or gas is released from the balloon, the pressure will decrease.
A balloon collapses when air is removed because the air pressure inside the balloon becomes lower than the air pressure outside the balloon. This pressure difference causes the balloon to shrink and collapse.
Yes, air pressure can affect a hot air balloon. A decrease in air pressure can cause the balloon to rise higher, while an increase in air pressure can cause it to descend. Pilots can adjust the altitude of a hot air balloon by manipulating the amount of hot air in the balloon.
A balloon collapses when air is removed from it because the pressure inside the balloon is higher than the pressure outside. As the air is removed, the pressure decreases inside the balloon causing it to shrink.
Air escapes a balloon when the pressure inside the balloon is greater than the pressure outside, causing the air to flow out through the opening of the balloon. This process continues until the pressure inside and outside the balloon equalize.
The pressure inside a balloon is created by the air molecules contained within the balloon pushing against the walls of the balloon. As more air is blown into the balloon, the number of air molecules increases, leading to a higher pressure inside the balloon.
Adding more air molecules to a balloon increases the number of collisions between the molecules and the balloon walls, thereby increasing the pressure inside the balloon. This increase in air pressure causes the balloon to expand until the pressure inside matches the pressure outside.
When you blow air into a balloon, the pressure of the air you are adding is higher than the surrounding air pressure inside the balloon. This increase in pressure causes the rubber of the balloon to stretch and expand. As you continue to blow more air, the balloon grows in size until the pressure inside the balloon equalizes with the pressure outside.
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.
If you let the air out of a balloon, it will deflate and decrease in size as the pressure inside the balloon equalizes with the external pressure.
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.
