Why do helium gas balloons rise up in the air? Since the balloon would rise if released, this buoyant force must be greater than the weight of the helium-filled balloon. In other words, the weight of the helium-filled balloon is less than the weight of the volume of air it displaces, which means that it is less dense than the air it displaces. So there is a net force upwards on the balloon, equal to the difference in weight between the balloon and the volume of air that it displaces. That the helium-filled balloon experiences a net upward force means that it can lift an object whose weight does not exceed this net force.

- Unfortunately, no one has followed a balloon up to see what really happens up there as far as I know. And on top of that, you have to keep adding air without tying a knot to over-inflate a balloon down here at sea level. It's hard to say whether the knot stays intact when a helium balloon explodes way up there.

- The helium will be compressed, however, thus much more helium is required to increase the mass sufficiently to overcome the density of the surrounding air -- far more helium than is required in a normal helium-filled party balloon.

How far does a helium balloon go in the sky when you let it go outside? Report Abuse. I can't tell you the exact height... I'd imagine mile or a mile and a half. However, I can tell you that the balloon would pop when the air pressure outside the balloon would become too low to hold in the high air pressure inside the balloon.ow far does a helium balloon go in the sky when you let it go outside? I let two go today for my cousin who died and one for a kid who died in a car crash 2 weeks ago.

- Pitch Burst is like a tankless dunk tank. A balloon is filled with whatever is appropriate (water, slime, confetti, etc.). Then the balloon is placed in the basket above a person sitting in a chair. When the target is hit, the balloon pops over the person.

Article:               Why do helium balloons float? Print Article: Why do helium balloons float? Print If you have ever taken an air-filled ball into the pool you may have noticed that it popped up to the top of the water and floated. That’s because air is lighter than water. Even when you add the weight of the ball itself, it is lighter than the amount of water that would fit in the same space. This is called buoyancy. Helium is even lighter than air. A liter (about a quart) of air weighs about 1.25 grams (much less than an ounce) — that’s not very much. But a liter of helium weighs even less — only 0.18 grams (a tiny fraction of an ounce). A balloon that’s 1 foot (30 centimeters) in diameter holds about half a cubic foot of helium, which is the same as 14 liters. This means the balloon will weigh about half an ounce (14 grams) less than the same sized balloon filled with air. So buoyancy goes to work, and just like the ball in the pool, the balloon floats upward. ‹ › × ×

Why does a hot air ballon rise???? The balloon will float until the density of its gas equals the density of the surrounding air. The density of the air decreases as altitude increases; because of gravity; gas molecules are more sparse at higher elevations. The air is thinner at high altitudes.

- As soon as a latex balloon is inflated, Helium atoms begin escaping through the microscopic pores in the balloon wall. As Helium atoms continue to escape from the balloon, the size of the balloon decreases until eventually there is not enough Helium left inside the balloon to make it float.

Myth: Helium makes your voice high-pitched Myth: Helium makes your voice high-pitched. A friend just pointed out an interesting misconception that I hadn’t thought about. When you inhale helium, your voice sounds higher. It turns out that your voice isn’t actually higher-pitched! At least, not in the way that we think it is. The reasoning is a little convoluted…. read on.

Respiratory distress If you let go of the rubber sheet, the volume of the bottle decreases. This creates a high pressure in the chest cavity. Air will rush out of the balloon to once again equalize the pressure. This is how expiration works. Your diaphragm relaxes, your chest cavity shrinks, and the air in your lungs gets pushed out.

Why Does the Balloon Move Forward in an Accelerating Car? The air in the car has a higher density in the back of the vehicle than it does in the front. This means that the net force on the balloon due to collisions with the air will be in the forward direction. Really, this is an interesting idea. Just think about gas in a stationary and non-accelerating car.

Altitude of the Highest Manned Balloon Flight An educational, Fair Use website. A balloon is a bag filled with heated air or a light gas so that it rises and floats in the air. A balloon rises because the heated air or gas inside is less dense than the surrounding air. There are two chief kinds of balloons: hot-air balloons and gas balloons. Hot-air balloons are mainly use for sporting and they rise because the air inside the balloon is warmer and lighter than the surrounding air.

When balloon put into a hot water what will happens to the molecules inside? r=a gas constant. t=temperature. When a balloon full of air (a gas) is heated the temperature rises. We know that r and n are constant so all we have to look at the relationship between temperature and pressure/volume.t~p and t~v. Therefore as temperature goes up pressure and volume will both go up.hen a balloon full of air (a gas) is heated the temperature rises.

Balloon Weather Predicting the wind. Hot air balloon flights rely on the wind being light for the first few hours after dawn and to decrease before dusk. Both of these situations can provide the opportunity for an enjoyable and safe balloon flight. For a safe balloon flight surface winds must be less than 10 miles an hour during the hour after dawn or before dusk.

- Hot air balloons fly because the air inside of the envelope is hotter than the outside air. By using propane-fueled burners, the air is heated, and the balloon ascends. To descend, the air inside the balloon must be cooled by either letting the envelope cool on its own or by opening the vent at the top of the envelope to let some of the hot air out.

Why do helium balloons rise and fall? Why do helium balloons rise and fall? At one point in the afternoon they were dropping but later in the evening it was fully upright again. ... The weather did go from a little rainy and overcast to dry and slightly clearer skies later. Likely many droplets of water adhered to the helium balloons, when the weather was rainy, and made them heavier. When the water evaporated the balloons became lighter and rose again.

- In other words, it must lighter than air. Filling a balloon with the sa…me air that surrounds it will mean it cannot possibly be lighter than air (at best it will be the same weight). But the weight of the balloon alone will make it heavier.

- Helium filled latex balloons only float for a couple of days because the Helium is constantly escaping through the walls of the balloon. Latex balloons are made of natural rubber. When natural rubber is formed into a latex balloon, the walls of the balloon inevitably have small microscopic pores or holes. Although these holes are too small to be seen by the human eye, they are about 1000 times larger than an extremely small Helium atom.

- 0.9% argon. 0.1% other gases (like carbon dioxide) Air is well mixed, so we do not usually talk about oxygen being lighter or heavier than air. Helium, on the other hand, is much lighter than air (nitrogen and oxygen), so that is why a helium-filled balloon goes up. At higher altitudes, the air is thinner (less atoms in the same volume), but the relative amounts of nitrogen and oxygen are the same.

- Thus even the air inside would be heavier than the equivalent mass of uncompressed air outside. Therefore it also makes sense to use a material that does not stretch. In order to make the balloon float, we must fill it with a gas that is not as dense as the air that surrounds it. Helium is ideal because the molecules are spread out much more than the molecules in the surrounding air -- and is therefore lighter (fewer molecules means less weight for a given mass of gas). Moreover, the material used in helium-filled balloons (party balloons) is wafer-thin and extremely light.

- This equation shows that as you heat the air in the balloon T 2 >T 1 (i.e. T 2 /T 1 >1) you get a positive force (F>0) which means that the force is up and the balloon rises. In summary, hot air rises because it is less dense than the surrounding air. Answer 2: Hot air pushes out on the air around it, and thus becomes less dense.
