I think that the hot air balloon was not a transportation in old times. The wright brothers invented an airplane that looked a bit like a glider, so there are chances that the glider might be used for transportation.
A hot air balloon.
The hot air balloon changed the world's method of transportation. This balloon was now a method of travel that didn't exist before.
An older kid should be able t blow a bigger balloon because a younger kid would have less breath and would therefore blow the balloon up slower and the older kid would be able to blow the bigger one. Also, the more air in the balloon the harder it will be to blow it up.
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.
The answer to this lovely question is Propulsion!
the method of transportation are cars, airplanes, bus, train, walk, bicycle, air balloon, camel, horse, boat, etc. please press like if you approve of this answer :)
trains, cars, buses, boats, planes, hot air balloon,come on its not that hard!Type your answer here...
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.
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
By glider do you mean like paper airplane?? it is held up by air pressure,,This will not work on the moon. There is no air there.
