1) Combustion is the scientific word for burning. In a combustion reaction a substance reacts with oxygen from the air and transfers energy to the surroundings as light and heat. The products of a combustion reaction are called oxides.
2) Combustible matter used to maintain fire, as coal, wood, oil, or gas, in order to create heat or power. something that gives nourishment; food. an energy source for engines, power plants, or reactors: Kerosene is used as jet engine fuel.
3) The lowest temperature at which a substance catches fire and undergoes combustion liberating heat and light is called ignition temperature.
4) The substances which have very low ignition temperature and can easily catch fire with a flame are called inflammable substances. Examples of inflammable substances are petrol, alcohol, Liquefied Petroleum Gas (LPG), etc

Answer:
The process of burning something is called combustion
material such as coal, gas, or oil that is burned to produce heat or power is called fuel
The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark
The substances which have very low ignition temperature and can easily catch fire with a flame are called inflammable substances. Examples of inflammable substances are petrol, alcohol, Liquefied Petroleum Gas
