The flash point of a liquid is defined as the temperature at which enough vapor is generated from the liquid to form an ignitable mixture with air. Specifically, this means that when the liquid reaches this temperature, it can produce vapors that can ignite if an ignition source is present.

This definition is critical for understanding fire safety and hazard assessments related to flammable liquids. It helps in determining the safe handling, storage, and transport of these substances to prevent accidental ignition. Knowing the flash point is essential for firefighters and safety personnel, as it guides appropriate responses to incidents involving flammable materials.

The other options describe related but distinct concepts. For example, the notion of no vapor forming pertains to a temperature below the flash point, while the temperature at which a liquid becomes gas refers to the boiling point, and the concept of no combustion occurring does not accurately define the flash point in an operational context.
