Are there any topics in physics that concerns fire? I need it for some essay.
Here one to start you off http://science.nasa.gov/msl1/combustion_why.htm - the science of burning
Another topic is that of entropy: the second law of thermodynamics states that all things will spontaneously move to states of greater disorder. As objects burn, they move from highly structured physical and chemical states (a stick of wood), to low energy and disordered states (ash, smoke, water vapor and carbon dioxide). The "2nd Law of Thermodynamics" ends up being one of the most important laws of Physics.
