A "thermal".
I have seen model air plane hobbyists fly over a hot parking lot or street in the summer because the "thermal" lets they stay aloft longer.
Hot air balloons can fly because hot air rises. When the air inside the balloon gets hot, it rises above the cooler air around it, and it lifts the balloon and any cargo and passengers with it.
they are alike because they both fly in the air
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
Hot air balloons fly because hot air is lighter than cold air, causing the balloon to rise. By heating the air inside the balloon with burners, the hot air inside becomes less dense than the cooler air outside. This temperature difference generates lift, allowing the balloon to ascend.
depends on how big the air balloons is
The hot air inside the balloon expands, making the hot air balloon fly.
Hot air balloons can pick up and fly from just about anywhere. As long as the surface is flat a hot air balloon can fly from it.
A monkey that can fly is a hot air baboon.
The hot air inside the balloon expands, making the hot air balloon fly.
the hot air is more dense then the actual air
i think it takes a long time for a hot air balloon to fly
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
Yes they were first to fly the first hot air balloon
An aeronaut flies a hot air balloon

You can't physicly fly, but you can ride in air planes and hot air balloons.
the mechanical advantage of a hot air balloon is this that we can use it in many good ways like it is for individual flight for every one, and can be use at any time but it depends on the air resistance + gravity because if the gravity is low the hot air balloon would fly far and far in the air and if the gravity is hifgh it would unable to fly and in air resistance if the air is high it would be difficult for a hot air balloon to fly and if air resistance is low it would be difficult for hot air balloon to fly in the air
