What is steam containing water particles in suspension known as?

The correct answer is wet steam. Wet steam refers to steam that contains water droplets or particles mixed in with the vapor phase. This condition often occurs when steam is generated from water that has not reached a complete vaporization state or when it cools and condenses during transport. The presence of these water particles in suspension significantly affects the thermal properties and efficiency of the steam.

Dry steam, conversely, is composed entirely of vapor without any water particles. Theoretical steam typically refers to an idealized condition of steam that doesn't exist in practical scenarios, while superheated steam is steam that has been heated beyond its saturation point, containing no liquid water and offering higher thermal energy. Therefore, wet steam is uniquely defined by its combination of both vapor and suspended liquid water, which is crucial in various applications, including heating and energy generation processes.
