Difference Between Gas and Steam
Difference Between Gas and Steam
On many occasions, the term gas is often confused with vapor, because both are in a gaseous state and have similar characteristics. However, there are some important differences that separate them.
How they are formed
Gas is formed from a combination of atoms or molecules, which move in all directions and completely fill any space provided to them. On the other hand, vapor is formed when a liquid substance evaporates due to the action of heat, forming particles in a gaseous state.
Pressure and temperature
Gas has a specific pressure and temperature, and can be easily compressed or expanded. Vapor, on the other hand, is at a specific pressure and temperature only at the points where it is formed, since if it expands, it cools and condenses back into liquid form.
The importance of water
Water vapor is an essential element In nature, since it is part of the water cycle. As water evaporates, it turns into vapor, and then, as it cools and condenses, it falls again as rain, snow or hail. On the other hand, gases such as oxygen, hydrogen or natural gas are not found in nature in a liquid or solid state.
Conclusion
In summary, although gas and vapor are in a gaseous state, they have important differences in their formation, behavior and use. It is important to know these differences to be able to use them appropriately and avoid confusion.
