According to an experiment, a paper basin was boiled with water over a candle flame. The paper did not burn as the water boiled and turned to vapor, decreasing in volume. Once all the water had evaporated, leaving the paper dry, the paper then burned due to the candle flame. The requirements for burning are oxygen, fuel, heat source, and for the burning point of the material to be reached. In this experiment, the wet paper could not act as a fuel for burning until all the water had evaporated and the paper dried out.
