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 does heating the air in hot air balloon make it rise?
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).
What kind gas is used in hot air balloon?
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.
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 makes hot air balloon rise?
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.

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.
