Which of the following describes superheated steam?

Superheated steam is characterized by its temperature being higher than the boiling point at the given pressure of the boiler. When water is converted to steam in a boiler, it can reach its boiling point (saturated steam), but if it continues to be heated without increasing the pressure, it transitions into a superheated state. This additional heating allows for more efficient energy transfer in turbines and other steam applications since superheated steam has a higher thermal energy content compared to saturated steam.

This definition aligns with the phenomenon whereby superheated steam has the ability to perform work more effectively because it is free of moisture, unlike saturated or wet steam, which contains water droplets that can damage equipment. The other options describe either different types of steam or conditions that do not align with the definition of superheated steam.
