When thinking of a balloon, it's best to think of two different chemical compounds that do not mix, the balloon itself and air. What makes the balloon pop is that the pressure of the air exceeds the force of the chemical bonds of the balloon. In order for a chemical reaction to take place, you need to start off with one set of chemicals that become a new set of chemicals.
However, when a balloon pops, no new chemicals are created. All that happens is that the electron bonds of the compound we know of as the balloon break.
Burning is a chemical change.
Physical, because the balloon did not have a change in its chemical composition when it broke.

Burning sulfur, or burning anything, is a chemical change.

Burning sulfur, or burning anything, is a chemical change.
Burning a candle is a chemical change. During the burning process, the wax of the candle reacts with oxygen in the air to produce carbon dioxide, water vapor, and heat. This chemical reaction results in the formation of new substances with different properties from the original wax, indicating a chemical change rather than a physical change.
Burning is always a chemical change. Melting is a physical change.
