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
What is the difference between a hot air balloon and a gas balloon?
a hot air ballon uses the hot air to rise as the hotter air has lower density while a gas ballon contains a light gas such a s helium and is not released while in flight only added
Why does helium belongs to group 8 while it has 2 electrons in its outer shell?
Helium belongs to group 18 elements along with other noble gases. All noble gases except helium have completely filled s and p orbitals. Helium has completely filled 1s orbitals and hence is kept along with the noble gases.
What is the difference between a ship travel and a balloon travel?
A ship travel is travelling with the use of a ship or boat while ballon travel is travelling using a Hot air ballon or ballon.
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.
Why does helium float?
Helium molecules are lighter than most air molecules in the atmosphere (mostly nitrogen and oxygen) therefore they are prone to rise while heavier molecules move downward.
How is the helium in the tank different from the helium in the balloon?
Helium balloons are usually mylar, a metal-coated plastic film while blow-up balloons are usually latex. Helium balloons are usually filled with helium of a decent purity, while blow-up balloons basically have the same gas mixture as the atmosphere around us. A little less oxygen and a little higher humidity if inflated by humans, exactly the same if inflated by a pump. Helium balloons will fly or float in the air, while blow-up balloons won't.
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
Why does a helium balloon lower after a while?
That would happen after it loses a certain amount of helium.
What forces are acting on a balloon tied with string to the ground?
If you need a one word answer, then I think "buoyancy" is what you're looking for. Buoyancy is caused by falling air pressure with altitude. Air pressure at sea level is over 14.7 pounds per square inch (2000 pounds per square foot!). You can feel this pressure by pulling on a suction cup. Because air pressure drops with altitude, the force from air on the top of an object is less than on the bottom. If the object has very low density (such as a helium-filled balloon), this difference in force is enough to push the object up.
Helium-4 and helium-3 are?
isotopesHelium-4 and helium 3 are isotopes and each have 2 protons. Helium 3 only has 1 neutron, while helium 4 has 2 neutrons.
Do sulfur and helium have similar chemical properties?
No they do not. Sulfur is a reactive solid, while helium is a nonreactive gas.
