Why does a balloon blown up with cold air falls o the ground but one balloon blown up with helium floats upward?

Helium is lighter than air so it floats. Cold air is fairly "heavy'" so it sinks to the bottom Average density of air + baloon is greater than surrounding air so it falls to highest density option ie downwards.


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]


Which is stronger A blown up balloon or a balloon waiting to be blown up?

I'm not very sure but I think thatthe balloon waiting to be blown up would be stronger, because inflated balloons can often pop easily.


How long will balloons float filled with exhaled air?

When a balloon is blown up by mouth, it will not float, but fall to the ground. This is because the air inside is the same density as the air outside. For a balloon to float up into the air, it must be inflated with a gas that is lighter than air - such as helium.


Can balloons blown up by mouth fly?

Balloons blown up by mouth can fly briefly due to the air pressure inside causing them to float for a short period of time. However, they will eventually lose air and fall back down. helium-filled balloons are typically used to make them float for longer periods.


Did any change happen to the shape and the volume of a balloon when air was blown into it?

Yes, when air is blown into a balloon, its shape will change from deflated to inflated. The volume inside the balloon will increase as more air is added, causing the balloon to expand and become larger.


Can a deflated balloon be blown up again?

Yes, a deflated balloon can be blown up again by adding air or helium to it using a pump or by blowing into it with your mouth. The balloon will expand and return to its original shape and size when inflated.


Why are balloons so squishy?

Balloons are squishy because they are made of thin, elastic material like latex or rubber that can expand and contract easily. When air is blown into the balloon, the material stretches to accommodate the air, giving the balloon its squishy feel.


What happens to balloons when they are let go?

well it depends what type of balloon it is if it is filled with helium it will float higher and higher until it will pop under the air pressure. but if it a ballon filled with normal air it will just float back down or get blown away if there is wind


What kind of air is used when you blow a balloon up?

When a balloon is "blown up" with your mouth, you are just passing "air" which is mostly Nitrogen, Oxygen and Carbon Dioxide. When a balloon is blown up so that it can float, then Helium gas is used. Helium gas is lighter than air, allowing the balloon to float. Other gases, such as Hydrogen are also lighter than air, however they are either dangerous or expensive to produce. For example, hydrogen is explosive. Helium is both inexpensive, and inert.


Did the two balloon get lighter or heavier when air was blew into them?

The balloons would become heavier when air is blown into them because the additional air adds weight to the balloons. The increase in weight is due to the added mass of the air molecules inside the balloons.


Could you improve your juggling skills in soccer by using a helium filled soccer ball?

No. Helium floats up. but if you meant the mouth blown yes. But you can get those soccer balls inside a net.
