The ignition temperature is affected by the chemical properties of the flammable liquid. When a flammable liquid is in its liquid state, it will not ignite. It will only burn when in its gaseous state.In addition to ignition temperature, other properties associated with the flammability of a liquid are its flash point, flammable range, and vapor density.The flash point is the temperature at which a flammable liquid vaporizes and is therefore able to ignite.Liquids with a flash point under 40 Â°C are considered combustible liquids. Gasoline has a flash point of about -45 Â°C.he ignition temperature is affected by the chemical properties of the flammable liquid. When a flammable liquid is in its liquid state, it will not ignite. It will only burn when in its gaseous state.
