Because the rubber became to pliant with heat
A hot air balloon is a machine that allows people to fly. It is comprised of a gigantic balloon attached to a basket where people stand. Under the balloon is a gas burner that lets out a large flame. The flame fills the balloon with heat, expanding it and enabling it to fly.
A Balloon needs hot air to rise, the flame, which is gas burning, heats up the air in the balloon. As Hot air rises above cooler air the balloon takes off.
As to the reason a hot air balloon floats has already been explained, I will answer your question regarding the flame. The gas burner provides the flame which is placed just in the mouth of the ballon, when lit it provides more heat to the cooling air in the balloon causing the balloon to maintain altitude.
hot air balloons work the best in cold temperature. the reason why is because if the outside temperature is close to the temperature in the hot air balloon, it will be as if the flame isn't on. if it is cold outside, the flame makes a much bigger impact and the balloon will go up faster.
Well it has a gas fueled flame and the flames heat makes the balloon part fill up with hot air. Hot air rises so the hot air balloon will float into the sky like a helium balloon would.

If a balloon is inflated and tied closed, then held over a flame, it will surely pop. The heat of the flame will melt the rubber that makes the balloon.

The answer is fairly simple, while some believe that a balloon bursts when near hot air because the balloon simple melts, it actually has to do with the pressure inside the balloon. When near hot air, the air inside the balloon expands slightly, causing a change in pressure, and causing the balloon to burst.
That flame is the source of heat for the hot air in the hot air balloon.
Why does the balloon with no water break in the flame? And balloon with water not break? The flame heats the rubber of both balloons. The rubber of the balloon without water becomes so hot, that it becomes too weak to resist the pressure of the air inside the balloon. When water inside the balloon is placed in the flame, the water absorbs most of the heat from the flame. Then, the rubber of the balloon does not become very hot. Because the rubber does not become hot, it does not weaken, and the balloon does not break. Water is a good absorber of heat

The plastic skin of the balloon will start to melt, and the air inside will suddenly burst through, causing the balloon to pop.

The piece of equipment that put the flame up into the balloon is called the 'burner' in most parts of the world. It is also sometimes called a 'heater'.

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.
