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.

a balloon originally does not have any air INSIDE it. hence,when air is forced in side it, the balloon expands (as the balloon is stretchable) at a limit, the balloon gets big enough and then it is knotted. But if we force more air into it, the balloon will burst. After it is knotted, the pressure inside and outside the balloon is the same.

This question is quite confusing, but nonetheless I'll attempt an answer. The air around us is constantly pushing against everything; atmospheric pressure. when you blow air into a balloon, you're pushing gas molecules at high pressure into the balloon. These air molecules crash into each other and the walls of the balloon, causing it to inflate. The air pressure in the balloon is higher than atmospheric pressure; or it would be crushed. This is a really hard topic to understand- hope this helps!

Atmospheric pressure is the weight of the air above any point on the earth.

the amount of force presses on a certain area is known as pressure so when you blow air in to the balloon your giving pressure on a certain place.

Does air pressure tell you how heavy air is?

Yes because when when you put a balloon in the air the balloon will tell you if its heavier or lighter.


What happens to a balloon on a hot day and what might happen if it gets to hot?

When air is heated, its volume increases. If you fill a balloon with comparably cold air and then let it touch hotter air, the air inside will expand and thereby increase the pressure on the balloon membrane. If this pressure gets too strong, the balloon might pop.


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.


Does heat from a candle change air pressure inside a bag?

yes because pressure that is confined by a container such as a balloon will increase if the balloon is heated.


What happens when you put a balloon on a water bottle and put it in hot water?

Air inside the bottle expands when the bottle is heated. Some of it leaves the bottle until the pressure of the heated air remaining in the bottle equals the pressure of the air in the room. The balloon is then placed over the neck of the bottle and prevents any more air from entering or leaving the bottle. The air inside the bottle cools to the temperature of the ice water. The cooler air inside the bottle takes less space (volume) than it did when hot, so it sucks the balloon inside the neck of the bottle. Air pressure inside the bottle causes the balloon to stretch and enlarge until the air pressure inside the bottle, including the air in the balloon, has the same pressure as the air in the room.

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.


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


Does air pressure tell you how heavy air is?

Yes because when when you put a balloon in the air the balloon will tell you if its heavier or lighter.


What creates pressure?

Pressure inside of a balloon is created by the movement of the air molecules against the inner surface of the balloon. The more air inside the balloon, the more molecules that are hitting the same surface are, so there is more pressure.
