Some chemicals, called ____, have flammable vapors that will self-ignite when exposed to air.

Question

Quizplus · Accepted Answer

Pyrophorics are substances that ignite spontaneously in air at or below 55 degrees Celsius. Therefore, they have flammable vapors that can self-ignite when exposed to air. Polymers are large molecules made up of repeating units, and while some polymers are flammable, not all of them have these spontaneous ignition properties. Oxidizers are substances that promote the combustion of other materials, but they do not have flammable vapors themselves. Vaporizers are devices that convert liquid or solid substances into a vapor or gas, and are not chemicals with inherent flammable properties.
