What differentiates superheated steam from saturated steam?

Superheated steam is indeed characterized by having a temperature that is higher than its boiling point at a given pressure. This means that it has been heated beyond the point of saturation, where it exists as a liquid and vapor mixture. When steam is superheated, it possesses additional heat energy that allows it to remain in a vapor state even at higher temperatures.

This property makes superheated steam useful in various industrial processes, such as in turbines, where it can drive mechanical energy generation efficiently. This increased temperature does not change the pressure at which the steam exists but rather gives it a higher thermal energy content, which can be utilized for heating or work purposes without the risk of condensation that could occur with saturated steam.

The other choices do not accurately describe superheated steam. For instance, superheated steam is generally not visible, as steam is typically invisible in its gaseous form. Its composition does not include more water particles; instead, it is completely in the vapor phase, whereas saturated steam has a mix of liquid and vapor. Furthermore, superheated steam has applications beyond refrigeration systems, extending into power generation and various heating applications in industrial settings.
