What is ignition tempareture
Answers
The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion. The temperature at which a chemical ignites decreases as the pressure or oxygen concentration increases. It is usually applied to a combustible fuel mixture.
The ignition temperature of a substance is the least temperature at which the substance starts combustion.
Substances which spontaneously ignite in a normal atmosphere at naturally ambient temperatures are termed pyrophoric.
Hey!
Ignition temperature is the temperature to which a substance should be heated before combustion occurs. A fuel like coal or wood would start burning if they are heated to their ignition temperature.
