A material that is flammable catches on fire from a minimal source. For example, propane can catch fire from just a tiny spark.

A material that is combustible or combustile is any material that will burn but requires a more dominant source. For example, wood is combustile, it burns, but it needs more than just a spark to do so.

All flammable material are combustible but not all combustible material are flammable

Both flammable and combustible mean apt to burn.

Flammable catches on fire. Combustible explodes. Boooyah!

Capable of igniting and burning is a combustible gas. Any compressed gas meeting the requirements for lower flammability limit, flammability limit range, flame projection,etc. All flammable substances are surely combustible, but all combustible substances are not essentially flammable.

A combustible liquid is flammable and will burn or explode and a true noncombustible liquid will not ignite. Thats whats up right there

Not flammable at room temperature, but combustible.

Actually, Diesel is not flammable, it is combustible. The difference is the flash point. Diesel does not flash until 143 degrees Fahrenheit. Anything between 100 and 200 is combustible; less than 100 is flammable. Compare it to "gasoline" which has a flash point of -42 F (I think).

A flammable material has a lower flash point (100F or below) while a combustible material has a flash point of 100F or HIGHER. In other words, it's a lot easier for a flammable material to catch fire than a combustible one because of the minimal amount of energy (heat) required to get it going versus the higher requirement of a combustible material.

Phosphorus is combustible which means that it is flammable.

Many are. Hydrocarbons as a class.CH4is methane and is combustible.

Flammable, combustible, corrosive: not determined, but very probable not. Einsteinium is a moderate reactive metal.

Yes, it can. Flammable or combustible means that it can catch on fire. Anything that can catch on fire is hazardous to one degree or another.

Combustible means it will burn but it's difficult to ignite. Wood is combustible. Flammable items will burn and they're easy to ignite. Gasoline is flammable. "Inflammable" is an old term that means the product will burn. Back then they didn't differentiate on ease of ignition, so a can of roofing tar--which is extremely hard to ignite--and a can of acetone--which is very easy to ignite--were both marked Inflammable.

Flammable vs. CombustibleThe words flammable and combustible have been around a long time and are constantly being interchanged with each other which is confusing.Combustible means that something will burn.Flammable also means that, BUT... its meaning goes beyond that. Flammable does mean something will burn, but tremendously faster and much more violently.Therefore, spray paint, before it dries is highly flammable.On the other hand, after spray paint has dried and cured, it would only be considered combustible, not flammable.

Combustible fabrics can catch on fire and noncombustible cannot.

Magnesium is flammable; after burning magnesium oxide is formed.

If something is combustible, it means it will be flammable. Gold can be melted, but it is not a flammable substance.
