Hot air makes the balloon go higher. That's why it's called a hot air balloon
you don't
By puting more hot air into it thus creating lift. hot air rises cold air lowers, so when the hot air is traped it has no were else to go but up so it brings the hot air balloon with it. And to decend a flap at the the top of the balloon opens by itsefl to let hot air out and to let you down.
The density of hot air is lower than air at low altitudes, but the air at higher altitudes is very thin. A hot air balloon can only rise until its density equals the surrounding air.
What are you, a retard? Even my 5 year old sister knew the answer to this. Hot air is lighter than cold air, thus the balloon with hot air rises higher than the cold air around it.
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
Hot air
Because the hot air balloon will keep on going up because the hotter the air gets the higher the hot air balloon will go!

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.

Because hot air rises, the warmest air in the balloon is at the top of it. As time passes the balloonist has to fire the burners to maintain the temperature of the air in the balloon, and to prevent it being squeezed put by the higher pressure of the cold air surrounding the balloon.
the higher you go the lighter the air is.

In hot air, particles are moving faster due to the increase in heat. This makes hot air lighter than cold air so the hot air will rise. When you put hot air into a balloon, the hot air will try and rise to the top. This allows the balloon to float in the air. Eventually the air will cool and sink back down which is why it's important to continuously pump hot air into the balloon to keep it up. Hope this helps! :)
