The hot air inside the balloon expands, making the hot air balloon fly.
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
Yes, it is possible to fly with balloons by using a hot air balloon or helium balloons, but flying with small party balloons is not feasible for human transportation.
Hot air balloons
You can't physicly fly, but you can ride in air planes and hot air balloons.
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.
neither..... they float with the wind! :-)
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.
Hot air balloons generally fly better with a little breeze, they don't fly well in hot weather.
Hot air balloons fly due to the principle of buoyancy. As the air inside the balloon heats up, it becomes less dense than the surrounding cooler air. This difference in density creates a lifting force that allows the balloon to float 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.
i dont know its used as hot and cold put together and fly
depends on how big the air balloons is
