What is the term for the temperature at which a liquid fuel produces sufficient vapors to support combustion?

The term for the temperature at which a liquid fuel produces sufficient vapors to support combustion is the flash point. The flash point is a critical concept in fire science because it indicates the minimum temperature at which the vapor concentration above the fuel will ignite when an ignition source is present. This means that, at or above this temperature, the vapors produced can mix with air and be ignitable.

The boiling point, while related to the temperature of a liquid turning into vapor, does not necessarily indicate whether those vapors can ignite. The fire point is indeed a related concept but refers to the temperature at which a liquid fuel will not only flash but will continue to burn for at least 5 seconds after being ignited. Stability point is not a recognized term in this context, making flash point the most accurate answer to the question regarding the ignition potential of liquid fuels.
