Does helium float or sink?
Helium is light and it will float / rise.
Does helium float or sink in air at room temperature?
Helium is lighter than air. So it will float in air.
Does helium contract in cold weather and cause a helium balloon to sink and if warmed will it rise again?
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain
Why do balloons decrease in size after a while?
Why does a balloon go down after a few days?A balloon goes down after a few days because the helium can pass through the skin of a balloon which then reduces the size of the balloon and the balloon then slowly reaches the floor after loosing all its helium.If you need any more help visit www.wikipidia.comThey loose air somehow.
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.
Does a balloon float or sink on water and why?
a balloon float on water

Will the helium football be light then a aired football?
yes. think about balloons: a ballon with helium will float while a balloon with good ol' air will sink
Does helium float or sink in air at room temperature?
Helium is lighter than air. So it will float in air.
Why does helium rise and regular air sink?
A balloon filled with helium floats and a balloon filled with regular air falls to the ground because helium has less density than air so the air causes the balloon to sink because there are more molecules in it. The helium has less molecules in it so the balloon rises.
Why don't normal balloons stay in the sky?
Due to the weight of the balloon. A balloon is merely a capsule full of air so it will fall to the ground as the balloon weighs it down. A helium balloon will rise into the air because helium is less dense than normal air (i.e. it weighs less). The air inside the balloon is the same density as the air outside. The balloon material itself is heavier than air, which causes the balloon to sink. If you decrease the density of the trapped air, such as by heating it or replacing it with hydrogen or helium, the balloon may become even lighter than the balloon material and an equal volume of normal air, in which case the balloon will float or rise.
How do you control a helium balloon to travel and stop wherever i want?
You could add a weight to make the balloon float level (that is it doesn't float up and away and doesn't sink to the ground) and then use wind to blow it where you want. Eg by blowing though a straw. You would probably have to do this inside.

Why does a hot air balloon rise when it is heated and sink wen it is cooled?
If it is cooled its gets extremely cold from the helium,and when the heat is in the balloon it keeps it warm when its in the helium
Why don't sulfur hexafluoride balloons float?
The air is too strong, which makes the balloon sink, along with the weight of the balloon's material.
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
