A hot air balloon is powerless, relying on the winds for locomotion, while an airship has a motor, allowing it to drift with its own power.

In rising, a hot air balloon works the same way as a helium balloon : the hot air inside is less dense than the surrounding air outside the balloon. The heavier outside air pushes below the balloon and forces it upward. To come down is easier in a hot air balloon. Unless it is continually reheated, its temperature reverts to that of the surrounding air and the balloon settles back to the Earth under its own weight. Vents that release the heated air (like venting helium in a helium balloon) is an alternative to increase the speed of descent.
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
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.
A person can legally own one, but I would assume that it would not be allowed into the air without special permission.
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
with out the hot air the balloon would not rise
air is heavier than balloon, air rises
The air in the balloon will cool , and the balloon will start to decend.
