ummm are you an absolute poo!!! hot air expands and is therefore lighter! and will therefore cause the ballon to rise, just as the concept between Hydrogen in Hydrogen Ballons! the Hydogen is smaller and therefore lighter!!!!! maaa!!!!! IM 6 YEARS OLD!!!!!

When does a air balloon rise?
A hot air balloon rises because when hot air is added it is intended to rise and when the hot air balloons wants to land, hot air is decreased.
Why can air balloon rise to the sky?
it can rise because of the helium and the gases help make it rise to the sky
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
Why does the balloon rise?
because it contains helium that is lighter than air
Why would heating the gas in balloon make the balloon rise?
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
Why is an hot air balloon called a hot air balloon?
Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
What is the use of air in air balloon?
with out the hot air the balloon would not rise
Why would heating the gas in air balloon make balloon rise?
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
Why do certain gases allow a balloon to rise?
Because the gases filling the balloon are lighter than the surrounding air.
Why does a balloon need hot air?
Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.
How does a hot-air balloon rise?
The upthrust on the balloon is greater than the weight of the balloon. Thus, it rises upwards. The upthrust on the balloon is greater than the weight of the balloon because the air inside it has a lower density than the surrounding air.
Why did they call it the hot air balloon?
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
