What is a flash point?
It is the lowest temperature at which a flammable liquid can receive an ignition source and be ignitable. However, once the ignition source is removed, the flammable nature may cease and the flame stop. At temperatures slightly higher, it is when an ignition source is introduced and the ignition source is removed that the flammable liquid continues to burn regardless of the ignition source. The lowest temperature at which a flammable liquid (e.g. gasoline) becomes capable of catching fire in the air. The correct term applied to non-liquids is the autoignition temperature or kindling point.
Is nitrogen gas at high temperature and pressure flammable is there is no temperature and pressure at which nitrogen gas can be flammable?
Nitrogen gas is not in itself flammable, and does not have an auto ignition temperature.
Can a flammable liquid self ignite without an ignition source?
yes.
Why vapours of flammable substances pose such a serious hazard?
It is not the flammable liquid that ignites, but the vapors (or vapours for our British cousins) that ignite. Vapor can travel a considerable distance from the liquid to an unforeseen source of ignition, and flash back when ignited. They can fill a large area, with a resulting LARGE fire when ignited. The distinction between flammable and combustible is the "flash point" the temperature at which the liquid gives off an ignitable vapor- flammables have a flash point below 100 degrees F. Many flammable liquid vapors are heavier than air, and can settle into the bilges of a boat, awaiting ignition.
What is the auto-ignition temperature of the flammable mixture?
It is normally referred to as the 'flash point'.
What is a clear liquid density 1 at room temperature non flammable?

What flammable liquid gives off vapors at below room temperature?
Propane and butane
What is meant by flammable bituminous liquid?
Simple: a liquid which is flammable.
Is it true that a liquid that can burn is flammable?
If a liquid is flammable it will burn. Flammable means can catch on fire.
How will a package of flammable liquid be identified?
Class 3 Flammable PlacardClass 3 Flammable Liquid label
What is ment by the term flashpoint in relation to fuels?
It is the lowest temperature at which the vapour of a flammable liquid will ignite in air. The flashpoint is generally lower than the temperature needed for the liquid itself to ignite
Is ketone a flammable liquid that gives off vapors at below room temperature?
No one ketone is gas at room temperature.
