In the absence of gravity there is no force to push or pull the balloons. Helium balloons only float up in the Earth’s atmosphere because the volume of air that they displace is heavier, and is pulled downwards more strongly, effectively pushing the balloon up and out of the way.
If a balloon is floating in the air, would it rise in the complete absence of atmospheric pressure? This question may seem difficult to answer, but the answer is actually quite simple. A helium balloon has a connection with the atmosphere and is supported by that gas. So, if the atmosphere and balloon were to disappear, would a balloon rise? It is a great question, and one that has been puzzled by scientists for decades.
If the air around the balloon were to suddenly cease to exist, helium balloons would be forced to explode in less than a second. This process would happen because the balloon’s pressurized air was moving at a much higher velocity than the surrounding air. Once the balloon exploded, the air molecules in it would continue to move at lower velocity until they reached a vacuum in space.
If there was no air surrounding the balloon, it would rise because of buoyancy. The weight of helium plus latex/rubber is less than the buoyant force of air being displaced upward. If the balloon was heavier, it would sink, but not enough to prevent it from rising. A balance scale with the heaviest thing on the bottom would result in a lower energy state.
If an empty balloon is submerged in water, then it will float. But if a balloon is filled with helium, then it will rise. And if the air balloon were to be submerged in water, the weight of the empty balloon would fall. That is the way gravity works. If the air balloon is filled with helium, it would rise, but if there is no air, the empty balloon would fall.
What happens to a helium balloon in zero gravity?
In the absence of gravity there is no force to push or pull the balloons. Helium balloons only float up in the Earth’s atmosphere because the volume of air that they displace is heavier, and is pulled downwards more strongly, effectively pushing the balloon up and out of the way.
What would happen to a helium balloon in space?
A helium-filled balloon can float very high up into the atmosphere, however, it cannot float up into outer space. The air in Earth’s atmosphere gets thinner the higher up you go. The balloon can only rise up until the atmosphere surrounding it has the same weight as the helium in the balloon.
What happens to a balloon when atmospheric pressure decreases?
So… If the temperature is constant, if pressure goes down, volume will go up (balloon expands). If T is constant, and the pressure goes up (say you hold the balloon underwater), then V will go down (balloon shrinks). If the volume is constant (say, an aerosol can) and the temperature goes up, then P goes up.
What makes a helium balloon rise?
The balloon rises because of buoyancy. The force (weight) of the helium plus the latex/rubber downward is less than the buoyant force of the volume of air displaced by the balloon acting upward. This means the weight of the balloon material was not great enough to cause the balloon to sink in the air. Hope this helps.
What would happen to a helium balloon in outer space?
The air molecules in this space balloon would expand at an extremely rapid rate, quickly pushing the rubber walls past their elasticity limits, causing the balloon to explode.
Are helium balloons affected by gravity?
Claire Donald answered on 14 Jun 2018: Helium itself isn’t affected by gravity as it is a gas and not a solid object. Although, if you think of a helium filled balloon, the balloon itself is being pulled down by gravity because its an object.
How do helium balloons still go upward when gravity pulls them down?
It’s only moving up because of gravity. The surrounding air is heavier than the helium so it pushes past the balloon to get advantage low as it can, which gives the helium no other choice but to go up.
Why do helium balloons float against gravity?
Helium floats because it is buoyant; its molecules are lighter than the nitrogen and oxygen molecules of our atmosphere and so they rise above it. In the car, it’s the air molecules that are actually getting pulled and pushed around by gravity as the result of the accelerating frame.
What would happen if a helium balloon was released on the moon?
“But on the moon, there is no air, so there’s nothing for the helium to rise above,” says Marc Rayman, an engineer at NASA’s Jet Propulsion Laboratory. Unable to escape even lunar gravity, which is one sixth that of Earth’s, the balloon would plunge to the ground.
What would happens to a balloon if the pressure decreases?
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.
How does atmospheric pressure affect a balloon?
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 could cause the volume of a balloon to decrease?
Explanation 1: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down. At room-temperature the helium balloon is lighter than air with the same volume of the air, which makes it go up. At low temperatures its volume is too small, so it is heavier than the same volume of air.
When the atmospheric pressure is increases on a balloon the volume of the balloon?
At a given temperature the pressure of gas reduces to 75% of its initial value and the volume increases by 40% of its initial value.
What causes helium balloon to rise?
The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the weight of the helium plus the balloon fabric is lighter than the air it displaces, the balloon will float in the air. It turns out that helium is a lot lighter than air.
How do you make helium balloons rise again?
Reviving Helium-Filled Balloons The same amount of helium is still inside the shell of the balloon. Simply move the balloon to a warmer place. The helium molecules get an energy boost, loosen up, move away from one another and expand. The balloon fills out and floats again.
Would A Helium Balloon Rise In The Complete Absence Of Atmospheric Pressure – Answers & Resources From The Web
Why does a helium balloon rise? – Physics Stack Exchange
Putting helium in a balloon per se doesn’t make the balloon float; rather, the helium provides a force to push the sides of the balloon away from each other, which causes it to inflate. When the balloon inflates, its volume increases. And it is this increased volume that causes the buoyancy. More volume -> more air displaced -> more buoyancy.
Helium balloon: What happens when you let go – Zephyr Solutions
So as a latex helium balloon rises, the outside air pressure diminishes, while the pressure from inside of the balloon remains the same. This causes the elastic material of the latex helium balloon to expand. As the latex expands, the helium balloon increases in volume, thereby increasing its buoyancy.

What causes helium weather balloons to expand as they rise?
Answer (1 of 3): Lower air pressure at higher altitudes. Gravity pulls everything down, including air, so it gunks up in the bottom, thus having more pressure (that’s the same reason there’s more water pressure deeper down). As a Helium balloon rises, its internal pressure stays the same (it lea…
• Why, and how high will a helium balloon rise? When buoyant force on balloon equals its weight, it will stop accelerating upwards. (Buoyant force = displaced-weight-of-air, so for same volume of balloon, this decreases as it rises because air is becoming less dense).

36.39 — Helium-filled balloon – UC Santa Barbara
Helium, which has a mass of 4.00 g/mol, has a density of 0.164 g/l. Thus, a one-liter balloon of helium can lift a mass of (1.18-0.164) = 1.02 g. Of course, this would include the mass of the balloon skin itself, and we are assuming that the pressure inside the balloon is not significantly greater than the surrounding pressure of 1 atm.
A balloon filled with helium does not rise in air indefinitely but …
When a balloon is filled with helium, there is an inner pressure because of which the balloon expands more and more as it goes higher. But as the balloon goes higher, the atmospheric pressure also decreases. This is why the balloon ultimately stops after reaching a certain height.
As the balloon raises, the pressure outside the balloon falls. Since the balloon is essentially in equilibrium, the pressure inside the balloon will also drop and the volume will increase. When the volume is greater then the max-imum balloon diameter, it will bust. To do this calculation we need a model
