Homonym: smoke (Fume)
Smoke is a visible mixture of gases and tiny solid particles that are produced when materials burn. It is often associated with fire and can come from various sources, such as wood, coal, or tobacco. The composition of smoke can vary depending on the material being burned and the conditions of combustion, including temperature and oxygen availability.
Smoke can have different colors, such as gray, black, or white, which indicate the type of material burning and the efficiency of the combustion process. In addition to being a byproduct of fires, smoke can also impact air quality and health, as it contains harmful substances that can irritate the lungs and eyes.
