Solution:
Concept- Substances that can be easily ignited by flame are called flammable substances.The ignition temperature is the lowest temperature at which a substance ignites and undergoes combustion, releasing heat and light.
If something is flammable, it means that it can be set on fire, such as a piece of wood. However, flammable means that the substance is capable of igniting without the need for any ignition.
Substances that have a very low ignition temperature and can be easily ignited by a flame are called flammable substances.
Examples of flammable substances are petrol, alcohol, liquefied petroleum gas (LPG), etc.
We can therefore state that flammable substances have a low ignition temperature which is less than
. Hence, the correct option is (2).
