Why does wet helium balloons fall?
Helium filled balloons eventually fall because the helium molecules escape from the envelope of the balloon, both at the neck of the balloon and through the material of the balloon itself. The same occurs with air-filled balloons but air-filled balloons do not float to begin with -- they fall to the ground no matter how much air you put in them. In order to float, the gas within the balloon must be lighter (less dense) than the gas outwith the balloon. Inflating a balloon with the same density of gas that surrounds it will not make it float upward because the weight of the balloon alone will make it fall under gravity. Moreover, the elasticity of the balloon compresses the gas within, making it much denser, and therefore heavier.
Can you fill helium balloons with normal air?
No it doesn't have helium. A hot air balloon derives it's lift from heated air, which is less dense and therefore lighter than normal air. A helium balloon derives it's lift from helium, a gas which at normal temperatures is less dense than normal air. So both fly 'lighter than air' but for different reasons.
Why does a helium balloon rise in air while ordinary balloon filled with air does not?
A helium balloon rises into the air because the density of the helium is lesser than the density of the air, therefore, the balloon rises, trying to reach above the air. Helium is lighter than air, or to be more precise, less dense. Helium gas weighs less than our atmospheric air so it floats. Same goes for hydrogen and a few other pure gases
Which gas inflates a balloon the longest carbon dioxide or helium and why?
Carbon dioxide will keep a balloon inflated longer than helium will, because its molecules are much larger and therefore less able to escape through the material of which the balloon is made.On the other hand, helium is much lighter so will give a balloon greater lift while it lasts.
How does helium make a balloon fly?
Helium rises because it is less dense than the air. If it is less dense then it will rise above the air until it meets a gas lighter than it. There are other gases lighter than air. You should experiment with other gases inside balloons.Less dense, or 'lighter than Air'.A one liter balloon filled with Helium and placed on a weigh scale will weigh less than the same balloon filled with air.Less *apex
What is the difference between a water balloon and a normal balloon?
A water balloon is filled with water, and other balloons are filled with air or helium.
How can you determine if a balloon is filled with helium gas or hydrogen gas?
Fill two balloons. One with hydrogen gas and the other with helium gas. Allow them to float on a piece of string. Taking a lighted/burning taper/splinter. , and burst the two balloons with the burning splinter. The helium filled balloon will just 'pop' and fall to the ground. The hydrogen filled balloon will 'pop with a flash of flame' So helium ; NO Flame Hydrogen ; A FLASH of FLAME.
Is balloons filled with hydrogen and oxygen?
If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium

Why doesn't a balloon float with air n floats wen it's filled with helium?
Helium is an element that is less dense than the air around it. This is because it is sooner on the periodic table (BY FAR) than all the other elements such as Nitrogen which is 70% of the air. As you should know, the elements have a weight and volume. Density is weight divided by volume, so elements sooner on the periodic would be less dense being lighter. So, the helium in the balloon and the weight of the balloon are together less than the air around it all, so it floats. Incidentally, balloons filled with air can indeed float, as many ballooning hobbyists know. Air expands as it is heated, and as a result it is less dense than the surrounding air. Balloons filled with hot air will float.
What is more buoyant air filled balloon or Styrofoam?
Under water they are as buoyant as each other but on land the balloon will float away and the Styrofoam will stay.
Can you fill helium balloons with normal air?
No it doesn't have helium. A hot air balloon derives it's lift from heated air, which is less dense and therefore lighter than normal air. A helium balloon derives it's lift from helium, a gas which at normal temperatures is less dense than normal air. So both fly 'lighter than air' but for different reasons.
What kind of air is used when you blow a balloon up?
When a balloon is "blown up" with your mouth, you are just passing "air" which is mostly Nitrogen, Oxygen and Carbon Dioxide. When a balloon is blown up so that it can float, then Helium gas is used. Helium gas is lighter than air, allowing the balloon to float. Other gases, such as Hydrogen are also lighter than air, however they are either dangerous or expensive to produce. For example, hydrogen is explosive. Helium is both inexpensive, and inert.
Why does a helium balloon rise in air while ordinary balloon filled with air does not?
A helium balloon rises into the air because the density of the helium is lesser than the density of the air, therefore, the balloon rises, trying to reach above the air.

Will a balloon filled with chlorine gas sink or float?
My dear friend. The answer to your question is yes. Neon is one of the so called lighter than air gases. It's lift capacity is sort of the same capacity as hot air gives. The only problem about it is the high cost of neon gas, plus like any other gas it will leak out after a while through the pores of the balloon's walls. Seems like it's not worth it to use neon gas in a balloon, although it will float nonetheless. Regards Marcio Nehrebecki
Why are some balloons able to float while others are not able to?
In order to float, a given mass (or volume) must be lighter than the equivalent mass that surrounds it. In other words, it must lighter than air. Filling a balloon with the same 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. It therefore makes sense to construct the balloon from the lightest possible material. Rubber is quite heavy but it is also elastic -- thus the air inside is compressed. 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. It also doesn't stretch as easily as rubber, so the helium is not compressed. Thus the balloon easily floats upwards with very little helium. The same effect can be achieved simply by warming the air inside the balloon. This forces the gas to expand, increasing the balloon's mass but without increasing its weight. With sufficient mass, the balloon eventually becomes lighter than the equivalent mass of the surrounding air -- and begins to float upwards. Filling a rubber balloon with helium is also possible, provided the balloon is small enough to begin with (making it lighter), and elastic enough to accommodate the amount of helium required to overcome the balloon's overall weight. 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.
What is helimum?
I assume that you mean Helium ... one of the Noble Gases. It is the second lightest Element, Hydrogen is the first. Being a noble gas, it does not burn so it is used in balloons. The noble gases do not readily combine with other elements to form other compounds ... they just 'stand alone.' A balloon filled with hydrogen can and does easily explode, but one filled with helium will not
