Liquids and solids mainly oil and wood are incapable of burning directly but must be converted first into flammable vapor by the heat For liquids to burn, atom or corresponding molecule of the prevailing ought to have kinetic energy and approach oxygen molecule (Horsfall, 2002) In case the underlying approaches are sufficient then it forms bond thereby releasing energy Conversely, in solid the molecules are normally joined together hence not mobile Within liquid it is normally rare for oxygen gas to penetrate thus the surface layer are commonly oxidize In solid fuel fire such as wood contain the volatile oils that normally evaporate and burns into corresponding flames Carbon is normally left after solid combustion then sublimates from the underlying surfaces of the hot substance thus combusting as a gas
Oxidation is a chemical change that mainly produces heat energy during the combustion process
