How does atmospheric pressure affect balloons?

How does atmospheric pressure affect balloons?

The molecules that are moving faster hit the walls of the balloons more often, and at a greater force. This means that it takes less hot air molecules to equal the same air pressure of cooler air molecules. The hotter, less dense air inside the balloon help it rise against the cooler, denser atmospheric air.

What causes the pressure that keeps a balloon inflated?

Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon’s inner walls. It is those collisions which keep the balloon inflated.

Why is the gas pressure inside an inflated balloon always greater than the air pressure outside?

The gas pressure inside an inflated rubber balloon is always greater than the air pressure outside because the pressure inside balances the atmospheric pressure as well as the pressure resulting from the walls of the balloon.

What is the atmospheric pressure inside a balloon?

One experiment shows that the balloon reaches a relatively constant pressure of 810 mmHg until it gets close to its maximum elasticity point and then increases to 820, 830 and finally 840 mmHg when it pops.

What happens to the pressure of the air inside a hot air balloon when the air is heated assume V is constant?

The fire heats up the air inside the balloon. The air rises and pushes on the inside of the balloon which makes the pressure higher on the inside than the outside. Since there is more pressure pushing up than pushing down, the balloon rises. →Explosion!

What would be true about the pressure if the volume of a balloon expands?

This implies that when the volume of the gas increases, its pressure decreases. For the given, the expansion of the balloon implies that its volume increases. Thus, according to Boyle’s law, its pressure is expected to decrease.

How does the air pressure inside the balloon compare with the air pressure outside the balloon?

A balance of forces: The pressure inside an inflated balloon is greater than the pressure outside it. The balloon is stable because the expanding force due to the pressure difference is balanced by the contracting force exerted by the surface tension of the rubber.

Is the pressure inside a balloon greater than the air pressure outside?

When a balloon is inflated Where do you think the air pressure is highest inside or outside explain your answer in 30 to 40 words?

The gas pressure inside an inflated balloon is always greater than the air pressure outside. It is because while inflating a balloon, we tend to push…

What happens to air in a balloon?

Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls. As a result, the size of the balloon increases.

What causes a balloon to burst?

At some point the pressure inside will become greater than the structural strength of the balloon material can maintain and the balloon will burst. This is directly related to the pressure inside the balloon versus the pressure outside the balloon.

What happens to the pressure inside a balloon when it expands?

the pressure outside, the balloon will expand. As volume begins to increase, the pressure of the air inside the balloon will decrease. Eventually the balloon will expand just enough that the pressures

Why does air blow out when it enters the balloon skin?

You need to take into account that the elastic tension of the balloon skin pulls inwards. This makes the pressure in the balloon greater than its surroundings. Since there is a pressure difference the air blows out when you penetrate the skin defeating the elastic tension of the balloon skin.

Why do weather balloons need to be checked?

Weather balloons need to be checked all the time to see if their volume does not expand to much because of low air pressure. If you rise into the atmosphere of the Earth air pressure starts to decrease and because of that objects such as, a balloon start to expand.
