What happens to a balloon when pressure decreases?

2 min read

Asked by: Owen Rai

As the balloon volume decreases, pressure inside the balloon increases. It eventually is able to balance the outside air pressure. You end up with a balloon filled with cold high density air. If you warm air it will expand and density will decrease until the pressure inside and outside the parcel are equal.

What happens to a balloon in low pressure?

Since there’s less air in the upper atmosphere, there’s less stuff pushing back on the balloon, and hence the pressure is lower, which allows the balloon to expand. Answer 4: If the balloon is flexible, then it expands as it rises to altitudes with lower air pressure.

What happens when the pressure in a balloon increases?

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 happened to the size of the balloon when the pressure decreases?

The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.

What is pressure in a balloon?

So, how much pressure can an inexpensive, thin-wall latex balloon withstand? 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.

Why do balloons deflate?

The lighter helium gas molecules leave the balloon faster than the heavier nitrogen and oxygen molecules can enter the balloon. Over a period of time, the balloon shrinks! Odd as it may seem, had the balloon been filled with a gas heavier than the gases in air (argon, for example), the balloon would eventually expand.

Does low pressure rise or sink?

So what does this have to do with high and low pressure? Well, high pressure is associated with sinking air, and low pressure is associated with rising air.

What causes the density of a balloon to decrease?

The density of a gas in the hot air balloon decreases as soon as the gas is heated because, with the increase in the temperature, the volume of gas… See full answer below.
