Question

The conditions necessary for combustion are?

• A. Presence of combustible substance
• B. Presence of supporter of combustion
• C. Attainment of ignition temperature
• D. All of these

Answer 1

The correct option is D

All of these

The explanation for the correct option:

Option(D): All of these

• Combustion is known as a chemical reaction in which a combustible or flammable substance reacts with atmospheric Oxygen to produce Heat.
• One of the necessary factors that are required for a combustion reaction to take place is the presence of a combustible or flammable substance i.e wood, petroleum, etc.
• Combustion can only take place when there is the presence of a supporter of combustion, i,e oxygen.
• For the combustion process, the fuel must be present at or above this ‘ignition temperature’, which is the lowest temperature at which a combustible substance simply undergoes combustion.

Hence, we can conclude that as all the conditions are given, are necessary for the combustion process thus, option (D) is the correct answer.
