• Combustion is the process in which a substance reacts with oxygen to give off heat. Example: a magnesium ribbon starts burning when heated in a flame. Given a combustible substance and oxygen, if the substance reaches its ignition temperature, it will start burning. Spontaneous combustion is a special case of combustion where a material burns without heat being supplied from an external source. Example: a piece of phosphorus suddenly starts burning when kept in a dish on a table. What could be the LIKELY reason for spontaneous combustion to happen? A . Non-metals absorb heat from the atmosphere more quickly than metals and are likely to combust spontaneously because of this. B. Materials that combust spontaneously have a special property - they need not reach the ignition temperature to combust. C. Spontaneous combustion is a process that requires only the presence of the combustible substance; heat and oxygen are not required. D. In the case of substances that combust spontaneously, a chemical reaction takes place which generates the heat required for combustion.
