What is one characteristic of a fog stream?

A fog stream is characterized by its ability to create water droplets with a very large surface area. This feature is significant because the increased surface area enhances the water's ability to absorb and transfer heat. When the fog stream is deployed, the large number of small droplets disperse effectively throughout the heated environment, allowing for better heat absorption as the water vaporizes, thus providing a more efficient cooling effect.

This property makes fog streams particularly useful in firefighting situations, as they can cover more area and penetrate into hotter, more confined spaces compared to other types of streams. This means that they maximize the impact of the water used, making them a valuable tool for firefighters in controlling and extinguishing fires effectively.
