Question

Inflammable substances have?
A. Low ignition temperature
B. High ignition temperature
C. Moderate ignition temperature
D. None of the above

Answer 1

Hint: We should know that substances that can easily catch fire with a flame are called inflammable substances. Now try to think what could be the ignition temperature for inflammable substances.

Complete step by step answer:
The definition of inflammable is something that catches fire easily or a person or thing that gets excited easily.
The substances which have very low ignition temperature and can easily catch fire with a flame are called inflammable substances.
Examples of inflammable substances are petrol, alcohol, Liquified Petroleum Gas (LPG), etc.

Therefore, we can conclude that inflammable substances have low ignition temperature and the correct answer to this question is option A.

Additional information:
Diesel is much less flammable than gasoline. In a car, it takes intense pressure or sustained flame to ignite diesel. On the other hand, if you toss a match into a pool of gasoline, it won't even touch the surface — it ignites the vapors above the surface.

Ethanol is a flammable, colorless, slightly toxic chemical compound sometimes simply referred to as alcohol. The combustion of ethanol forms carbon dioxide and water.

Note: You should know that flammable and inflammable do not mean the same thing. If something is flammable it means it can be set fire to, such as a piece of wood. However, inflammable means that a substance is capable of bursting into flames without the need for any ignition. The opposite of both words is non-flammable.
