a hot air balloon works when the hot air blowing from the bottom pushes up the balloon which lifts it up into the sky where it moves in the direction where the wind blows .
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Hot air makes the balloon go higher. That's why it's 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 :)
Hot air rises. That is how a hot air balloon works.
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.
Hot air makes a hot air balloon rise because hot air is less dense than the cooler air around it, so the hot air balloon floats on the cooler air around it.
ahhh hot air?? hot air rissies sooo when you put hot air nto a balloon it evenually rises
Well it has a gas fueled flame and the flames heat makes the balloon part fill up with hot air. Hot air rises so the hot air balloon will float into the sky like a helium balloon would.
the balloon works with the poplo force forcing it up
The upthrust exerted by surrounding air on the balloon.
The hot air from the fire pushes the balloon up, and putting out the fire makes it go down again :)
Hot air rises. By heating the cool air in the balloon using a propane heater, heats the air and makes the balloon rise
