Superheated steam is defined as steam that is above which temperature?

Superheated steam refers to steam that has been heated beyond its saturation temperature, which is the temperature at which water transitions from a liquid to a gas at a given pressure. When steam is at its saturation temperature, it can exist in a mixture of liquid water and steam. However, when the steam is heated further without an increase in pressure, it becomes superheated.

This additional heating allows the steam to have a higher thermal energy level and results in a lower density compared to saturated steam. Superheated steam is particularly important in power generation and industrial processes, as it improves the efficiency of turbines by preventing condensation and reducing the risk of damage to equipment.

The saturation temperature is therefore a critical concept in thermodynamics and power engineering related to steam systems, making it the defining temperature for superheated steam.
