What is the ignition temperature for an electric spark?

The ignition temperature for an electric spark is around 1,700°F. This temperature is crucial because it represents the minimum heat required to ignite various combustible materials when exposed to an electric arc or spark.

Understanding ignition temperatures is vital in fire safety and prevention, particularly in environments where electrical equipment is used. If the temperature of a surface or material exceeds this ignition threshold due to an electric spark, it can lead to combustion, resulting in a fire hazard. This knowledge helps in designing safer electrical systems, choosing appropriate materials, and implementing proper safety measures to minimize fire risks.

The other options listed represent temperatures that are higher than the known ignition threshold for an electric spark, which emphasizes the importance of accurate temperature knowledge in preventing potential fire hazards in various applications.
