What type of steam contains water droplets due to the condensation of some water molecules?

Wet steam is a type of steam that contains water droplets in addition to water vapor. This occurs because the steam is at or near the saturation point, allowing some of the steam to condense back into water droplets. The presence of these droplets indicates that the steam has not been completely vaporized, resulting in a mixture of steam and liquid water. Wet steam is often encountered in various steam systems, especially where the conditions are appropriate for condensation.

In contrast, superheated steam is steam that has been heated beyond its saturation point and contains no water droplets; it is entirely in vapor form. Dry steam, while it might seem similar to wet steam, specifically refers to steam that is entirely in the vapor state without any liquid present. Saturated steam is the state of steam at the boiling point, where it is on the verge of entering the wet steam condition but is not fully condensed. Therefore, the definition and characteristics of wet steam align perfectly with the question asked.
