Shopping For Birthday Balloons?
Most people are familiar with birthday balloons. Rubber balloons are filled with helium or air and come in a variety of colors. Mylar balloons are most often filled with helium; they have a metallic sheen, and have a variety of designs printed on them. Rubber balloons are also called latex balloons. These balloons often do not last long, because the helium leaks out through tiny pores in the rubber. Filling the balloon with plain air will cause it to last much longer, but of course, such balloons will not float. On the other hand, you may not want your balloons to last long past the birthday celebration; random balloons floating around the house can be annoying. If you do want them to last, however, and you prefer rubber balloons, you can ask if your store has any balloons that have been treated with Hi Float. Hi Float is a substance used to coat the inside of rubber balloons to prevent the helium from leaking out. Balloons treated with Hi Float last up to 25 times longer than regular balloons. If you want to go the mylar route, you’ll have a lot of options. There are many shapes and colors available. There are many super-sized mylar balloons as well, which can be exciting to receive. Mylar balloons also last much longer than untreated rubber balloons, because there are few tiny holes for the helium to slip through. Some can even last for several weeks! Be careful with mylar balloons around power lines, however; they can conduct electricity, and balloons that come in contact with the lines are often the cause of outages. Be careful around children with any balloons, because they can be a choking hazard when they’re uninflated or have burst. In addition, resist the temptation to breathe in the helium; when you breathe in helium, you’re not breathing in air, so it’s like you’re not breathing at all. You can asphyxiate, even die. And that wouldn’t make for a very happy birthday at all.
Why do hot are balloons have to be large?
Because they hold lot weight
How is possible for one tank of helium to fill 700 balloon?
Helium is stored under pressure, so a lot is packed into a small space. The gas in the balloon is at only slightly more than normal air pressure. The helium spreads out as it fills the balloons.
Why balloons are filled with helium?
Filling a balloon with enough helium for flight takes a lot of helium, hot air balloons only use hot air because it only takes a couple of tanks of propane to heat the air, which is much more cost effective than filling the balloon with helium. Airships use helium because they are used to stay in the air for extended periods of time, so it makes sense to pay for the helium to fill it once, rather than the propane to keep the air hot.
How do the elderly use helium?
What is doubtless the most common use of helium by the elderly is the getting and giving of helium balloons. "Older" people don't do a lot of mixed gas diving, inert gas welding or other activities like that.
Why do helium balloons lose air faster than carbon monoxide balloons?
It doesn't literally lose "air," because "air" is not what's inside.But I know what you mean ... you want to know why it losespressure faster, and goes limp and saggy.The molecules of helium are actually physically smaller than the molecules of any component of air, so they escape more readily and more often through the molecular structure of the rubber or mylar skin.(Tentative answer) Helium atoms are smaller than the molecules in air, so they are more likely to pass through the microscopic holes (imperfections) in the latex or mylar. Over time, the net effect is that helium leaves the balloon faster.You are probably referring to the escape of helium, He, from a sealed or knotted balloon.Yes, helium escapes from sealed rubber balloons very much faster than air does. This is because the rubber membrane of a typical toy balloon possesses many small holes or pores, of sizes ranging from smaller than that of a helium atom, to holes thousands of times larger (but still too small to clearly see with the naked eye). He, being the second-smallest atom (next to Hydrogen), passes through many more of these holes than Nitrogen, N, the principal constituent of air and which has an atomic radius many times larger than He. There are other effects at work besides atomic size, but atomic size alone will explain most of the faster deflation seen in He balloons, compared with balloons filled with room air.Helium atoms are smaller than air molecules. The Helium can creep between the rubber molecules in the balloon more easily and quicker than the bigger heavier air molecules.
What happens when hydrogen and helium mix?
Helium is completely inert, it is the most inert of all elements, and so it will not react in any way with hydrogen (or with any other element). So, if you mix hydrogen and helium, nothing happens. You have a mixture of hydrogen and helium. It's a lot lighter than air, you can make balloons that will float. Of course, you can do that with pure hydrogen or with pure helium, as well.
Does helium have a lot of pressure?
yes helium does have a lot of pressure.
Where can I find helium?
you find helium gas as a by product from the sun .you also find it in a form of alpha particle . but the form we often use today is found in the atmosphere but it only 0.005 of our amothsphere is helium gas because a lot of the helium gas flouts away.
Which gas is used to fill balloons?
Helium is normally used in balloons that float. Helium is the second lightest gas. Hydrogen is lighter, but it is also flammable and thus dangerous.When normal air is used to fill a balloon, the balloon will not be buoyant.If you fill a balloon with air from your lungs, there is a bit more water vapor and a bit more carbon dioxide and a bit less oxygen in the air inside the balloon, but that has a small impact on the buoyancy.The larger balloons that carry people are called hot air balloons because they are filled with hot air. They are buoyant because the hot air is fractionally lighter than normal air but there is a lot of it.Weather balloons and party balloons both use helium gas.As long as the gas plus the balloon is lighter than the air it displaces, the balloon will float in the air.Helium is normally used in balloons that float. Helium is the second lightest gas. Hydrogen is lighter, but it is also flammable and thus dangerous.When normal air is used to fill a balloon, the balloon will not be buoyant.If you fill a balloon with air from your lungs, there is a bit more water vapor and a bit more carbon dioxide and a bit less oxygen in the air inside the balloon, but that has a small impact on the buoyancy.The larger balloons that carry people are called hot air balloons because they are filled with hot air.

Can balloons hold more water or air?
Water. Because water molecules do not move around to much. How ever air molecules move a lot.
Why is helium used to fill balloons?
It is a matter of mass, weight, and density. A balloon filled with normal air will not rise. Air will rise in water, because it is less dense (bubbles). Helium on the other hand is lighter than air, so it too will rise when 'submerged' in it. The actual process is that the heavier air surrounding a helium-filled balloon will "displace it" and force it upward. Hydrogen is also less dense than air, but it is flammable. Helium is not flammable, has no smell or taste, and is not poisonous. So because it is the second lightest element, and the second most plentiful in the world (found in natural gas), it's a natural fit. ---- However, consider that while it may seem fun to have balloons that go up on a string, if they escape, then eventually they pop and it is likely that the burst rubber will fall into the sea. In the sea they are mistaken for food by turtles and escaped balloons cause much harm. Also being unreactive as an element and very light, most of the helium on earth has gone to the top of the atmosphere and escaped into space. The only helium we have is found as a byproduct of radioactive decay within the Earth. The element has very important uses in industry and science and wasting it on balloons is not a sensible thing to do. There is only a finite amount of helium available to us at any given time.
