What is the Difference Between Smoke and Steam?

🆚 Go to Comparative Table 🆚

The main difference between smoke and steam lies in their composition and formation. Here are the key differences:

  • Smoke: Smoke is a collection of airborne solids, liquids, and gases emitted when a substance is undergoing combustion. It is created from burning material composed of fine particles. Smoke can be produced by various sources, such as burning wood, coal, or other combustible materials.
  • Steam: Steam is pure water vapor, produced by boiling water. It can also be created by boiling water with other liquids, resulting in other vapors mixed with water. Steam is heated water vapor that has reached the gaseous phase of water.

In summary, smoke is a mixture of airborne particles and gases emitted during combustion, while steam is heated water vapor in its gaseous phase. Smoke is often visible as a cloud of particles in the air, whereas steam is a colorless and odorless gas that is not easily visible.

Comparative Table: Smoke vs Steam

The main differences between smoke and steam can be summarized in the following table:

Feature Smoke Steam
Origin Smoke is produced by the combustion of a substance, which releases solid, liquid, and gaseous particles in the air. Steam is generated by heating water to its boiling point, which causes it to transition from the liquid state to the gaseous state.
Composition Smoke primarily consists of gases and soot, but it also contains water vapor and other gases. Steam is essentially heated water vapor in the gaseous phase.
Color and Appearance Smoke is typically darker in color and can be visibility seen as it dissipates into the air. Steam is usually white and misty in appearance, and it becomes visible when the temperature drops.
Condensation Smoke does not condense but rather dissipates into the air. Steam automatically condenses if the temperature were to drop.
Inhalation Inhaling smoke can be dangerous and cause damage to the lungs. Steam is not dangerous to inhale.

Remember that the easiest way to differentiate between smoke and steam is to consider how they are produced and their appearance. Steam is generated from heated water, while smoke is a by-product of combustion. Steam has a white and misty appearance, whereas smoke is darker and can be seen dissipating into the air.
