What makes balloons float when they are full of air but not float when they are deflated?
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Why do balloons float up to the sky?
The balloons that float usually contain helium in them, which is lighter than air. This enables the balloon to float.
Why do helium balloons float better than just air balloons?
helium is less dense than air. :) so helium will float better than air
Will warming helium balloons make them float?
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
Can balloons float from the air out of your mouth?
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
Why can hot air balloons float?
which gas is in ballons
Why do hot air balloons float up?
Magic...
Why does a helium balloom float in air?
Helium is lighter than air. so balloons filled with helium will float in air
Why is air balloons filled with helium?
Because it is a safe gas that is less dense than air, thus balloons float in air
What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
Why do helium balloons fail to float?
Actually, they do float. They are lighter than air, so they are supposed to float.
