Because the rubber became to pliant with heat
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
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.
To increase enthalpy.the burner uses flames to heat the air so the balloon will rise
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.
Propane. This is what makes the flame that heats the air in the balloon.
When a balloon is held over a flame, the heat causes the air inside to expand rapidly. This increase in pressure can exceed the strength of the balloon material, causing it to burst. Additionally, the heat from the flame weakens the elasticity of the balloon, making it more prone to popping.
Heating a balloon can cause it to expand due to the increase in temperature. If the balloon is not made of flame-resistant material, it is likely to burst when exposed to the flame due to the buildup of pressure from the expanding air inside. This experiment can be dangerous and may result in the balloon popping and potential injury, so caution should be exercised.
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

That flame is the source of heat for the hot air in the hot air 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.

The air inside the balloon will expand due to the heat, causing the balloon to inflate. If the water is hot enough, the balloon may eventually burst due to the increased pressure from the expanding air.
This is because the gas inside the balloon expands due to the heat of the sun. Gases expand the most on heating. The volume of the gas becomes more then the volume of the inflated balloon and thus it burts.
