the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
Because the gas inside expands with the heat
The gas will expand as it is heated.
It expands until the temperature is high enough to compromise the balloon's skin.
metal is a solid that expands when heated also of course when liquids are heated and change state into a gas they expand but metal is cool because it expands before it changes state

When any state of matter is heated it expands.
The kinetic energy of the particles inside the balloon increase. This then expands the volume of the balloon.
It expands until the temperature is high enough to compromise the balloon's skin.
As the air in the balloon is heated, it expands and becomes less dense, or that is, becomes lighter. This then provides lift to the balloon and the basket. The reason the air in the balloon expands, is because as it is heated, the molecules of air move faster and spread out to fill the entire volume of the balloon.

physical change
In a nutshell, air rises and expands when heated. Through the use of a burner the balloon pilot heats up the air inside the envelope (the balloon itself), this air inside the envelope expands and rises, lifing the basket.
The temparature was higher and it caused more air pressure
