Smoke

Smoke is a mixture of tiny solid particles, liquid droplets, and gases produced when a material, like wood or tobacco, burns. It results from incomplete combustion, where not all fuel is fully burned, releasing a complex combination of chemicals. Smoke can carry harmful substances that affect air quality and health. Its appearance varies from light and wispy to thick and dark, depending on the burning material and conditions. Understanding smoke is important for safety, environmental health, and fire management, as it can obscure visibility and contain pollutants that are harmful to humans and the environment.
