The actual balloon isn't lighter than air, the only reason hot air balloons rise is because they are filled with hot air, which is lighter and less dense than cold air, causing it to rise. :)
Hot air balloons fly due to the principle of buoyancy. Heated air inside the balloon is lighter than the cooler air surrounding it, causing the balloon to rise. The burner inside the balloon heats the air, which expands and becomes less dense, lifting the balloon off the ground.

No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
A hot air balloon stays afloat because hot air inside the balloon is less dense than the surrounding cooler air, creating lift. As the air inside the balloon is heated, it expands and becomes lighter, causing the balloon to rise. By controlling the amount of hot air in the balloon, the pilot can control the altitude.

hot air rises; it is lighter than cool air It does not have to be Hot Air inside the balloon, unless you want that Balloon to rise up.Hot Air is less dense than Cold Air and hence the former is lighter.

Hot air is lighter. See the related link.

Hot air is lighter than cold air. If you fill a balloon with hot air, the air inside will be lighter than the air outside and therefore the balloon will rise (until the air inside gets cold again).
The hot air has thermal energy, and when the balloon is up in the air, it also has gravitational potential energy.

Hot air balloons fly because of the principle of buoyancy. The balloon is filled with hot air, which is lighter than the surrounding cooler air. This temperature difference creates lift, causing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can control the altitude.
No. The first hot air balloon was in 1783, but she did the witness of the launch of one.
