Fuel is defined as a substance that undergoes reaction with oxygen and produces energy. The process is called as combustion. The fuel can be liquid (kerosene), gas (methane) or solid (coal). The meaning of inflammable is that the substance has the ability to catch fire easily. Not all fuels are inflammable. Wood is one such example.
