anybody knows about the theory of flash points?

Question

i have some ... i took it from wikipedia... can anybody tell me more about theory of flash point ..... ?

Answer 1

1.The lowest temperature at which the vapor of a combustible liquid can be made to ignite momentarily in air.
-The point at which eruption into significant action, creation, or violence occurs: “The shootdown did not increase international tensions to the flash point” (Seymour M. Hersh).
2.Shouldn't it be called the Big Flash Theory since nobody was around to hear it? And can you hear anything in space? Any my point is universe has to come from somewhere. Now the new theory is that black hole do let the matter out at some point. For example: A black hole eats a star and lets out a gamma ray burst. Could that star be a galaxy in another universe? And the gamma ray burst is like a burp. There are many black holes in the universe. Maybe it is a way to compress data, so to speak. Our universe could be a part inside of an atom of another world, and so on. And I'm not religious, but that would NOT make us gods of the worlds within our own atoms. Because our own atoms will live a lot longer than us. We are just but an evolutionar step. Look at the Earths delicate eco-system. Our particles will be around forever, what are the odds of them all meeting back up? We will be obsolete at some point.
3.Every flammable liquid has a vapor pressure, which is a function of that liquid's temperature. As the temperature increases, the vapor pressure increases. As the vapor pressure increases, the concentration of evaporated flammable liquid in the air increases. Hence it is the temperature which determines the concentration of evaporated flammable liquid in the air under equilibrium conditions. Different flammable liquids require different concentrations of the fuel in air to sustain combustion. The flash point is that minimum temperature at which there is a sufficient concentration of evaporated fuel in the air for combustion to propagate after an ignition source has been introduced.

Answer 2

Combustible liquids evaporate. Their vapors will burn if the concentration of vapor in air is just right. As the temperature of the liquid is increased, the vapors are given off at a higher rate. At the flash point, enough vapor is mixed with air to enable it to be ignited by a spark. Almost immediately the vapor in air is used up, and the flame goes out.
