The hot air from the burner rises since it has little density, and then is caught in the balloon, which causes it to rise.

What 2 things that use hot air to rise?
hot-air balloons and birds in flight.
Why do hot air balloons rise with hot air?
Hot air is less dense than cooler air, therefore the balloon will rise (float) on the cooler air around it.
What makes a hot air balloon float?
A hot air balloon is able to float because the hot air being released into the balloon is less dense than the colder air surrounding it. Basically, the burner under the hot air balloons fills the balloons with hot air, enabling the balloon to rise through the cooler air outside.
What is the difference between a helium balloon and a hot air balloon?
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
Which gas do you use for hot air balloons?
Hot air is used for hot air balloons.
Why do you think hot-air balloons can rise into the air?
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Does helium rise?
yes honey, that's why hot air balloons rise
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 do hot air balloons rise with hot air?
Hot air is less dense than cooler air, therefore the balloon will rise (float) on the cooler air around it.
What source is used to fly hot air balloons?
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.

Will a balloon rise if the air inside is hot?
The heating of the air through the use of a burner is what makes balloons rise.
How high do hot air balloons go up?
they contain helium molecules which are lighter than the air we breath making the balloons rise
Why do balloons float up into the air?
At a hot air balloon festival, hot air balloons slowly fill and then rise majestically in the predawn sky. These hot air balloons fly because of two fundamental principles of physics: the ideal gas law and Archimedes's principle.

Why do we use warm air in a hot air balloons?
This is because of convection. Hot air rises and cool air falls which causes the balloon to rise.
