What is the key difference between fumes and mist?

The key difference between fumes and mist primarily revolves around their source and formation. Fumes are generally produced when solids are heated to a point where they release vapors. These vapors can condense into tiny solid particles upon cooling. Thus, fumes are often associated with high-temperature processes, such as welding or smelting, where metal or other materials release vaporized particles created from heat.

Mist, on the other hand, is formed when moisture in the air condenses into fine droplets, often due to changes in temperature or humidity. This condensation leads to the formation of small liquid droplets that can be suspended in the air.

Understanding this distinction is critical in the context of armament systems, as it helps identify potential hazards associated with handling materials and the environment in which armament systems operate. Knowing whether a substance is a fume or mist informs safety protocols, personal protective equipment requirements, and emergency response measures.
