No. Helium is not molecular it is a monoatomic gas.

Which has higher density balloon filled with water or helium?
I would say an air filled balloon if you fill it with just plain air. I am basing this on the principle of osmosis and diffusion. A substance such as a gas will travel from an area of increased concentration, such as a balloon filled with helium, to an area od decreased concentration, such as the room the balloon is in. If you fill the balloon with air identicle to that in the surrounding room it negates diffusion.
Will a balloon deflate faster in warm or cold temperatures?
A helium balloon of the same material will deflate faster. Helium molecules are smaller than those in regular air, so they'll seep through tiny holes and imperfections in the skin of the balloon faster. When using the standard PIN analysis - both helium and common air balloons were found to deflate at the same rate. To the naked eye, both balloons stuck with a pin deflated with a pop. However, if the balloons are left intact, the helium balloon will deflate faster. This is because the helium molecules are small enough to pass through the rubber balloon, and they gradually leak out.
Does helium come out of a balloon faster than air?
Yes. The reasons are helium is monoatomicand light and therefore at a particular temperature the helium atoms move faster and can diffuse out quicker than the larger molecules N2, O2 in an air filled balloon. (This is Grahams Law of gaseous effusion in practise)Gases are diffusing through theballoon membrane in both directions- the pressure difference is not really that great after all you can inflate a balloon using only lung power.Fill a balloon with a gas such as SF6 then it will inflateas the lighter faster moving air diffuse in at a higher rate than SF6 diffuses out
As a helium filled balloon rises in the air it becomes?
Larger (the air pressure is dropping as it rises).
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.
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.

Can you compress the same amount of helium gas in a larger balloon into a smaller balloon one third the size but make of stronger materal?
Yes, as long as it is still a gas.

Can helium be compressed why?
Helium can be compressed because it is a gas. Gases are basically spread out molecules, that is, the larger the container that they are in, the larger they spread out. They still have the same amount of molecules, but they are just spread wider. Therefore, they can also be compressed. As an example, think of 100 humans being the 100 molecules of helium. There are only 100 of them, but they could be spread out in a massive room, or they could be crammed into a tiny room.

How would air particles in a balloon at 0 C compare to air particles in a balloon at 100 C?
The individual molecules will be moving faster at 100 °C, than at 0°C. The molecules would also be further apart (ie. they would occupy a larger volume).
What will happen if a partially inflated party balloon were heated?
The air molecules would expand, increasing the pressure of the balloon. When anything gets cold, it contracts, and when heated, it expands. Atoms and molecules are always moving - when something is hot, the molecules are moving faster and greater distances. When something is cold, the molecules are still moving, just slowly and at much smaller distances. You won't see much a difference while it's partially inflated, though there would be one. You can see results more drastically by heating a balloon that is near completely inflated. The more air molecules that are in the balloon, the greater the expansion. In other words, the bigger the balloon and more air that's in it, when heated you will see a larger change in the balloon size.
What can make a balloon float besides helium?
It depends on what the balloon is filled with.A balloon may float if it is filled with any gas that is less dense than air: hydrogen, helium, even pure nitrogen gas. However, the weight of the balloon will determine whether it can be lifted by the difference in density. So the most effective lifting gases are hydrogen and helium. Helium is used because it is nonflammable and noncorrosive. Early German dirigibles (zeppelins) were filled with hydrogen, and some caught fire, notably the Hindenburg in 1937.Larger balloons can be lifted by hot air, which is less dense than cooler air. If the air cools again, it will no longer provide lift.
