It will rise because it has less density, so it tends to "float" on the denser, cold, air.The reason it is less dense is because when you heat air, its volume increases. Since density is mass/volume, the density decreases in this case.
Because when the air or water are heated their density becomes lighter than that of the cold air or water and so they rise up and the cold air or water goes down.
In a liquid (as solid particles in a liquid or in a lava lamp with two immiscible liquids) In the air, hot air rises, cold air descends (as in a hot air balloon)
Heat is the energy of the hot air. Therefore hot air rises
Hot air is less dense than cooler air, therefore the balloon will rise (float) on the cooler air around it.
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.

A liquid have random particles but they are still all joined together.
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.
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.

to make a hot air balloon rise you use hot air
