Does helium float or sink?
Helium is light and it will float / rise.
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
Does helium float or sink in air at room temperature?
Helium is lighter than air. So it will float in air.
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.
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.

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
How is the average density of a heluim balloon be changed to make it rise float at a constant level and sink?
you would have to deacrease the density. By doing so, you can float. I don't know bout constant level, but because the air in the balloon is more dense than outside air, the balloon will sink in air. p.s. i know you s.j.v students are probably reading this :)
What is the difference between having helium in a balloon and having air in a balloon?
Helium is lighter than air, so a balloon filled with helium will float. In contrast, air-filled balloons will sink because the density of air is greater than that of helium. Additionally, helium balloons will deflate faster than air-filled balloons due to its smaller molecular size.
What makes balloons float when they are full of air but not float when they are deflated?
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
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.
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
Will string float or sink in water?
Nope Most string should float on top of water becomes the string material is less dense than he water.
Why does not a balloon full of oxygen float?
A balloon filled with oxygen, like any other gas, will only float if it is less dense than the surrounding air. The weight of the balloon, the gas inside, and the container itself typically make the balloon denser than the air, causing it to sink. A helium-filled balloon floats because helium is much lighter than air.
Does helium float or sink in air at room temperature?
Helium is lighter than air. So it will float in air.
Does helium float or sink in water?
Helium gas is less dense than air, so it will rise and float in both air and water.
