What is the structure of smoke?

Smoke is a complex mixture of gases, liquid droplets, and solid particles produced by combustion. Its primary components include carbon dioxide, water vapor, and various organic compounds, along with particulate matter like soot and ash. The structure of smoke can vary depending on the material burned and the combustion conditions, leading to differences in color, density, and toxicity. Overall, smoke is a colloidal suspension that can disperse in the air, affecting visibility and air quality.
