Answer 1

Answer:

Please mark me as brainliest i need only 5 more

Explanation:

Bro i am not adding bread and food but i am using flashing point and flammeable point...

To understand the difference between flash point and fire point, we must first understand the context in which those terms are used.

Both terms - flash point and fire point - are used to describe liquids.

All liquids vaporize - that is, molecules of that substance evaporate, to form a layer of vapour molecules of that substance, right above (and in contact with) the liquid surface.

These vapor molecules, when they mix with the surrounding air, form a combustible mixture.

For a liquid, flash point denotes the lowest temperature at which, if a distinct source of ignition (say spark/fire) were brought in contact with the vapor-air mixture, the vapor (and the liquid surface in contact with it) catches fire.

Fire point, on the other hand, is the lowest temperature at which, even in the absence of an ignition source, the mixture (air-vapor and liquid surface) catches fire.

Two important things to be noted here are:

Below the flash point for a liquid, no burning occurs - this is because the liquid is unable to give off enough vapor to form a burnable mixture with air, at temperatures below the flash point. Hence, flash point is the minimum temperature at which the liquid gives off enough vapor to form a combustible mixture with air.

Since fire point is the temperature at which the vapor above the liquid catches fire even without ignition, it automatically follows that fire point > flash point.
