👉 Appears: fumes are a type of visual phenomenon that can occur when certain substances, particularly those with volatile organic compounds (VOCs), react with light or other environmental factors. These fumes often manifest as wispy, ghostly trails or hazy plumes that seem to emanate from surfaces or objects, giving the impression of smoke or mist. They are typically pale in color, ranging from white to grayish-blue, and can appear in various settings, from industrial environments to natural settings like caves or near chemical spills. The appearance of these fumes is often transient, dissipating quickly as the source of the reaction subsides or as the environment stabilizes. However, they can be a clear indicator of underlying chemical processes or contamination, making them both visually striking and scientifically significant.
