a helium balloon is forced upward by buoyancy. a object is forced upward by a force equal to the weight of the fluid it displaces. this also applies to gases. the gas helium is lighter than average atmospheric air, that is that equal volumes of atmospheric air and helium do not weigh the same. This means that the volume displaced by the balloon is heavier than the balloon itself. since the air weighs more it applies more force upwards on the balloon than the balloon applies downwards on the air, therefore it rises. However, a helium balloon will not go down unless a force such as large air resistance (heavy wind etc.) is applied to it. hope this helps.
What else can I help you with?
Is nitrogen a suitable gas to put in balloons?
Yes, nitrogen is a suitable gas to put in balloons. It is often used as an alternative to helium because it is non-flammable and does not deplete the Earth's helium supply. However, nitrogen does not have the lifting properties of helium, so balloons filled with nitrogen will not float.
What gas does the opposite of helium?
That would be sulfur hexaflouride. that weighs 6 pound, witch makes your voice go lower, if you inhale it. Helium is -6 pounds, which makes your voice go higher. there both safe to inhale, but i think you need a license to handle sulfur hexaflouride.
Why does helium change your voice?
Because Helium is lighter than the oxygen and other gases we breathe, when it passes through your vocal chords, it makes them vibrate quicker than the heavier gases like Oxygen-(8) and such. So because they cause your vocal chords to vibrate quicker, it tightens up your vocal chords and makes the pitch of your voice go up.
What happen when you placed the balloon near the can after rubbing it in your head?
When you rub a balloon on your head, it becomes negatively charged due to the transfer of electrons from your hair. When you bring the balloon near the can, which typically has a neutral charge, the negative charge on the balloon induces a positive charge on the side of the can closest to the balloon. This creates an attractive force between the balloon and the can, causing them to move towards each other.
Will a balloon filled with nitrogen will explode if a burning match is touched to it?
No, a balloon filled with nitrogen will not explode when a burning match is touched to it. Nitrogen is an inert gas and does not support combustion, so the match will go out before it can ignite the balloon.
Why do you have to hang onto your helium balloon?
Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.
What happens to gas when it is put inside a balloon?
It depends what type of gas it is. With air inside a balloon will just stay still, will be easy to lift and when you kick it like a ball it will slowly go up and then come back down again. If you have helium in a balloon, the balloon will try to go to the highest point it can get, if you go outside and let go of a balloon it rise and go far above the clouds until the balloon starts to wear out so the helium starts to slowly come out so the balloon slowly comes down.
How long does a balloon decompose?
When you let go of a balloon the air that is inside of it makes it fly up.It is impossible for it to go up to space.If its without helium then it takes about 6 days.
What is something that can go up quite easily but is harder to bring back down?
A helium balloon with no string.
How do helium balloons work?
helium balloons get filled with a amount of air in which is called helium it is used to make balloons float around in air. helium is a inert,gaseous element!!!!!yea i kenisha am smartHelium is less dense than air, therefore a helium-filled balloon will float in air.Helium is lighter that air, so it effectively floats on air. As a helium balloon is submerged in air, it rises upwards (like an air filled bubble in water).
If you fill 2 balloons one with helium and one in air which one would go down first?
the balloon with air will fall first because air is more dense than helium.
How does a hot air balloon go up and down?
Heat rises of it makes the ballon rises
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 does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
Why does cold air make helium balloons collapse when you take them outside?
Cold air molecules move slowly, while hot air molecules move quickly. That's why cold air contracts, weighs less, and go down, while warm air expands, gets lighter, and go up. The cold air inside a helium balloon would contract and make the balloon collapse. Otherwise, there would be a vacuum in the balloon.
What happens if you put helium in a balloon?
It makes your vocal cords go to a higher pitch witch reaches the exit of you oesophagus and exits your mouth disturbing the air particles making your voice a higher pitch. when i dummy it down this is the definition. It makes your voice high pitched! It can also make you lose consciousness and die from hypoxia (lack of oxygen) so make sure you just take a sip from the balloon.
Why does a helium balloon float into the sky when you let go?
Helium is lighter than air, therefore it rises upwards.
