Put a straw in the end of it and blow into the balloon. That should make it fly straight although make sure you don't use helium and make sure there is as little of wind around as possible. From Matthew
the temperature affects the balloon filled with air because if it is too cold it can freeze it, and cause the balloon to pop
Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
Because the thin skin isn't entirely air tight. A little bit of air is constantly leaking straight through.
yes
The air particles in the balloon compress due to the cold atmosphere in the refrigerator which causes the balloon to be smaller.
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
no its filled with hot air from a fire that is lit underneath the balloon.

air
Putting an air-filled balloon in a refrigerator will cause it to shrink.
No it decreases
A water balloon is filled with water, and other balloons are filled with air or helium.
The balloon expands.
Helium gas is lighter than air and hence balloons filled with helium will float in air.
No. Helium is lighter than air
