Flash Point Properties – At elevated temperatures, diesel fuel will begin to vaporize and become ignitable with an open flame.
Do Sparks have mass?
Actually, when a spark is thrown from a welder or a grindstone, it does not, as the questioner suggests, vaporize. Rather, a spark from these items is a red-hot speck of metal, which rapidly cools due to its lack of mass.
