HomeWhy does air rise when it is hot?
When air gets hotter, or when any gas gets hotter, it expands. This means its density will decrease; therefore, cooler (and heavier) air will push it up.

Heat is the energy of the hot air. Therefore hot air rises
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.
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
Hot air is less dense than cooler air, therefore the balloon will rise (float) on the cooler air around it.
Cold air does not rise like hot air. Cold air sinks. Hope this helps
to make a hot air balloon rise you use hot air
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.
The hot air from the burner rises since it has little density, and then is caught in the balloon, which causes it to rise.
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.
Hot air rises because it is less dense than cold air.
convection (studyisland answer)
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.
Because hot air is lighter than cold air.
Why do hot air baloons rise
Mostly get hot and rise.
hot-air balloons and birds in flight.
with out the hot air the balloon would not rise
A hot ballon rise in air.
Hot air has less mass which make it less dense, thus allowing it to rise over a cold air mass.
The actual balloon isn't lighter than air, the only reason hot air balloons rise is because they are filled with hot air, which is lighter and less dense than cold air, causing it to rise. :)
The air is less dense than the air outside.
yes honey, that's why hot air balloons rise
Hot air is less dense than cooler air. This makes it weigh less then the surrounding air so it rises.
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
