Simply put, the weather balloon is a lighter-than-air vehicle or aerosonde that provides lift to an instrument package to get it to altitude. The instruments thus situated can collect data which, when combined with other information from both similar and different sources, can be used to assess current conditions, and, as an extension, to forecast weather.

∙ 13y agoWhen air is heated, the density decreases. When the air in the balloon decreases to such a point that the combined density of the heated air and the balloon becomes lower than the density of the ambient air, the balloon rises.

Does a balloon grow when its hot ot cold?
A baloon will 'grow' when the air inside becomes warmer than the air outside. So it grows when it's hot.
Is the air inside the balloon less dense than the air outside the balloon?
No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.
Can you inflate a balloon in a bottle with a straw sticking out of the bottle why?
Yes you can if all conditions were perfect. By that I mean that the bottle would have to be a near perfect vacuum by sucking out the air from the bottle with the straw. The vacated air from the bottle would be replaced by the baloon stretching to fill the space left by the air. You would have no need to blow into the baloon as the vacuum would do the work for you.
Why does a hot air baloon float?
Raising the air temperature inside the envelope makes it lighter than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water
How does convection work in a hot air balloon?
When the air inside a hot air ballon is heated the hot air rises, which makes the ballon rise hope i helped ;)
How does a hot air baloons fly?
By the hot air that is created from a burner under the envelop (baloon).
What are the safety features of a hot air balloon?
lots of padding on the inside of the baloon basket ! :)
What is the air of hot air balloon?
It is the same as the air we breath, the only difference is that it has been heated, hot air rises above cold air and thats what lifts the baloon.
Why was the hot air baloon invented?
So that politicians would have someplace to dispel their internal pressure.

How much helium do you need to kill a person?
like 3200 oz which is equivelent of a hot air baloon.
In what way is a baloon like a stomach?
Your stomach is like a baloon in the way that it expands with air in it.
Why does a hot air balloon rise when the air inside is still heated?
Because hot air rises, so if there is hot air inside the baloon, the balloon will be compelled to ride because the air pushes against the balloon upward, and, long story short, the air wins. Hope this helped.
What is it about atmosphere on Earth for balloons to lift?
The earths atmosphere is denser than the helium found in a baloon therefore the baloon is lighter and is lifted above the denser air located in earths atmosphere. Which is why if you just blow up a baloon with air from your lungs it does not float. It would be the same density as the air outside of the baloon.
What has roots that nobody sees is taller than trees up up it goes yet never grows?
An hot air baloon.
How do you buy a lamborghini?
You must personaly know Mau Ze Dounge and have at least 75million dollars and own a hot air baloon.
