What are the components of smoke?

Smoke is a complex mixture of various components that is produced during combustion. The correct choice highlights the main constituents of smoke, which are particles, vapor, and gases.

Particles in smoke can include soot, ash, and other solid materials that are emitted into the air as a result of incomplete combustion. These particles can contribute to health problems and can affect air quality.

Vapor refers to the gaseous state of substances that may have been in liquid form during the combustion process, such as water vapor and organic vapors.

Gases are a significant component of smoke, encompassing a variety of chemical compounds created during combustion, including carbon monoxide, carbon dioxide, and other potentially toxic substances.

Understanding these components is crucial for fire fighters, as they must be aware of the hazards posed by smoke in different fire scenarios, including the potential for toxic exposure and the strategies for effective ventilation and suppression.
