Here's why:
* Flammability refers to a substance's ability to burn or ignite easily. It's essentially how readily a substance will react with oxygen to produce heat and light (fire).
While flammability is the key property, several other factors contribute to combustion:
* Oxygen: Combustion needs an oxidizer, and oxygen is the most common one.
* Heat: A source of ignition energy (a spark, flame, or heat) is required to start the combustion process.
* Fuel: This is the substance that reacts with oxygen.
* Chemical Composition: The type of fuel and its chemical makeup determine how easily it will ignite and sustain combustion.
In summary, while flammability is the primary property, combustion requires a combination of factors including a fuel, oxygen, and an ignition source.
