big kind of round and a cylinder basket
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.
Air= air in balloon solid= balloon and basket
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 :)
When a hot air balloon is filled with the hot air the air around the balloon is a lot denser. So by convection the balloon rises and the less dense air is replaced by dense air underneath it.
A balloon is an object that hovers and move with the wind.
The easiest way to describe compressed air propulsion: Blow air into a ballon (compress the air) then release the balloon. The balloon will take off (propulsion) due to the compressed air within.
It is a disordered motion.

D: The hot air inside the balloon becomes less dense than the air outside the balloon.
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
A balloon powered car is moves because the balloon pushes out air. Whenever something exerts a force on something else (in other words, the balloon is exerting force on the air), then the object being pushed always exerts an equal and opposite reaction force on the object exerting force on it (in other words, the air exerts force on the balloon). Because the balloon is attached to the car, when the balloon is pushed by the air, the car is pushed. The law that for every force there is an equal and opposite reaction force is Newton's Third Law of Motion.
with out the hot air the balloon would not rise
