What is ignition temperature, combustion , fuel ?

Academic Physics NCERT Class 8

Combustion is the same as burning. Substances or materials which undergo combustion are called fuels. Ex: wood, petrol

The lowest temperature at which a substance catches fire and undergoes combustion liberating heat and light is called ignition temperature.
