Question

Explain Combustion,Ignition temperature.

Answer 1

• ignition temperature :- the lowest temperature at which a substance catch fire.
• combustion:- a chemical process in which a substance react with oxygen to give off light and heat is called combustion.

Answer 2

Answer:

Combustion :Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. During combustion, new chemical substances are created from the fuel and the oxidizer. These substances are called exhaust. Most of the exhaust comes from chemical combinations of the fuel and oxygen.

Ignition temperature : The lowest temperature at which a substance catches fire and undergoes combustion liberating heat and light is called ignition temperature. In other words it is the minimum temperature at which a combustible substance such as air or gas, must be heated up prior to burning in the absence of any source of the heat.
