Question

Choose the correct statement about inflammable substances from the following statements. They have:
A) low ignition temperature and cannot catch fire easily.
B) high ignition temperature and can catch fire easily.
C) low ignition temperature and can catch fire easily.
D) high ignition temperature and cannot catch fire easily.

Answer 1

Hint: Ignition temperature is the minimum temperature that a substance must be raised to before it will ignite. And it can also define as the lowest temperature at which a combustible substance when heated takes fire in air and continues to burn.

Complete answer:
> Inflammable means something that can easily catch fire, that substance which possesses very low ignition temperature is called an inflammable substance. For example petrol, alcohol, liquefied petroleum Gas, aerosol sprays.
> When a substance starts burning, heat is produced and it helps to burn the substance continuously. The ignition temperature in different substances decides the quickness of catching fire.

Therefore the correct answer is C.

Note: Flammability is the ability of a material to quickly attach oxygen. Oxidation will make an item flammable. When something burns, it becomes rapidly oxidized, it depends on material. Some materials are easy to oxidize and some are difficult as some items are flammable in particular from matter. Flammable and inflammable do not mean the same thing. Flammable and inflammable are two words that cause confusion, they can differentiate by their ignition temperature. If something is flammable it means it can set fire to, such as a piece of wood.
