The answer is well this is my score in a row 127762 it took me 7 hours!But it was fun! :D
The longest someone has flown in the air is 50 hours!
A hot air balloon is hollow (naturally) and is filled with the hot air that gives the balloon lift. By surfing the web a bit, one can probably find a picture that gives at least a partial view of the inside. I would doubtless have been taken by someone in the basket of the balloon, but there may be a shot of a an airborne balloon at low altitude taken by someone on the ground.
Imagine inhaling to blow in a balloon. You will take in air, hold it in your mouth and blow it into the balloon. Some of it will be the carbon dioxide you were exhaling but most of it will be the air you just breathed in. So, the gas inside the balloon will be a mixture, that is, air.
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.
Most hot-air balloons use propane (a liquified petroleum gas) as fuel for burners which heat the air in the balloon. The heated air has lower density than the air outside the balloon, which gives it buoyancy and generates lift.
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.

It varies by balloon. If the balloon is spherical, the circumference is pi times the diameter. If you are asking what the skin is made of, it is usually coated, very light fabric.
air is heavier than balloon, air rises
