Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
Why do air balloons rise when heated air is trapped inside the balloon?
Warm air is heavier than cold air so it rises up.
What keeps hot air balloons aloft?
the hot air inside the balloon is what's keeping the balloon aloft. the explanation is hot gases or air is lighter than cold air so hot air will rise since it is lighter than the cold air.
What do they fill hot air balloons with?
Air heated with a flame, hot air is lighter than cold air and therefore rises above it like something light floating on water
Can hot air balloons get above the troposphere?
No because the air gets too cold for convection to happen, causing the hot air balloon to stay in place or even fall
Do balloons deflate faster in hot or cold air?
cold air because hot blowes them up
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
When balloons are filled with this they are lighter than air.?
Hot air, hydrogen or helium are lighter than cold air.
Why does cold air have a higher density than warm air?
Yes, cold air has a higher density than hot air, and that is why hot air balloons rise, it rises above the cold air. hot air is less dense than cold air^
Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
What happens to the air in hot air balloons?
It might pop. Maybe But i'm not really sure
If Two balloons a and b are filled with hot air and cold air respectively how would you compare their densities?
A<b
What happens in cold and warm air masses?
what happens in cold and warm masses pressure
Why do air balloons rise when heated air is trapped inside the balloon?
Warm air is heavier than cold air so it rises up.
What happens to the density of air as it's temperature increases?
Becomes lighter and rises, the principle of hot air balloons.
What happens with air pressure when the air is cold?
The air pressure is high when the air is cold, and it's sinking.
Why are air condition units often positioned close to the ceiling in hot countries and heaters close to the ground in cold countries?
Cold air falls and hot air rises. That simple. Think of hot air balloons.
