What is fire?
Fire is fast oxidation in flammable substances. How iron react with oxygen in the air, hydrocarbons react with oxygen not only they release chemical energy, thermal energy and light energy too. They release thermal energy and light energy because the arrangement of atoms are very fast. For example, candle's string reacts with oxygen in the air, makes carbon Dioxide, carbon monoxide, dihydrogen monoxide, Hydrogen Dioxide and etc. This is chemical change, but in Physical change, the wax of the candle will turn to liquid.
Chemical change:
The reaction or recombination of atoms
Physical change:
The change in state
