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.
What is the difference between a full and an empty balloon?
A full balloon contains more gas than an empty balloon (even an empty balloon contains a little air). Therefore a full balloon is heavier than an empty balloon (assuming the balloons are the same weight to begin with). However, if filled with a lighter-than-air gas, such as helium, the full balloon will defy gravity due to its increased buoyancy. The only other difference is that the skin of a full balloon will be stretched and will therefore be much thinner than the skin of an empty balloon. This stretching increases the pressure upon the gas contained therein, therefore the gas is compressed inside the balloon.
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.
Why do baloons float in air?
Balloons float in air because they are filled with a gas that is lighter than the surrounding air, usually helium or hydrogen. This creates a buoyant force that pushes the balloon upward, causing it to float.
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.
How do you fill a balloon with helium?
Buy a cannister full of pressurised helium (make sure you read the instructions on the cannister). Fasten a balloon over the nozzle, open the tap just enough to let helium out. Close the tap when the balloon is full.
Hypothetically if you could stand on the moon with a balloon full of helium and gently release it from your hands what would happen to the balloon and why?
Probably it would drop on the ground, because the moon has no atmosphere.
If you stack books on a sealed balloon full of air the pressure inside will?
Explode
Why when you explode a balloon full of hydrogen with a balloon full of oxygen do small droplets of liquid form?
because the hydrogen and oxygen react together creating water(the small droplets of liquid)
Is a balloon full of helium a compound element or a mixture?
A mixture: The walls of the balloon are not made of helium, and helium itself never reacts with any elastomeric material suitable for constructing balloons.
Is it bad to do the helium challenge?
A little helium isn't harmful, but inhaling an entire balloon-full can block oxygen to your brain, which might cause you to pass out. There has been at least one death from breathing helium from a pressurized tank instead of a balloon, too.
If empty barrel weighs 10 pounds what can you put in the barrel so that it weighs less?
You could put a flexible bladder (balloon) filled with helium in it. The classic answer to this old question is: Fill it full of holes.

Name of gas in air baloon?
If air is blown into a balloon then it will be full of air.If you want the balloon to float up then the gas you fill it with is not air but helium.[However please note that if a helium balloon escapes, it may burst and fall back to earth over the sea where it can harm sea creatures (especially turtles) who try to eat them - so please do not purchase helium balloons]
Do football's have helium?
NO! Footballs are not full with helium because if they were they would float up in the sky
