Which of the following is NOT a state of steam?

The correct response identifies "condensed steam" as not being a state of steam. To understand why this is the case, it is essential to clarify what the other states represent.

Dry saturated steam refers to steam that is in equilibrium with water at a specific temperature and pressure, where the steam is fully vaporized but contains no liquid water. Superheated steam, on the other hand, is steam that has been heated beyond its boiling point at a given pressure, meaning it is completely in the vapor phase without any liquid present. Wet saturated steam contains both water and steam, indicating that it has not completely vaporized; thus, it contains a mixture of liquid and vapor.

Condensed steam, however, implies a phase change back to liquid water. This term is not commonly used in thermodynamics in the context of the four primary steam states since it does not represent a state of steam but rather describes a scenario where steam has undergone condensation, transitioning back into the liquid form. Therefore, it stands apart from the other mentioned states which are all forms of steam in their gaseous condition.
