What does superheated steam have more of compared to saturated steam at the same pressure?

Superheated steam possesses more heat energy than saturated steam at the same pressure. This is due to the fact that superheated steam is steam that has been heated beyond its boiling point at a given pressure, thereby increasing its thermal energy without an increase in pressure or condensation.

When steam is saturated, it is at the brink of condensing into water, containing the maximum amount of moisture possible at that pressure. By contrast, superheated steam is devoid of any liquid water, making it drier and allowing it to carry more heat energy. This increased heat energy is significant in applications such as steam engines and turbines, where efficiency gains are achieved through the use of superheated steam.

The other options do not align with the properties of superheated steam. Moisture (the first option) would actually be lower in superheated steam since it is in a dry state. Density (the third option) does not increase; in fact, as steam is superheated, its density typically decreases. Pressure (the fourth option) remains constant when comparing saturated and superheated steam at the same pressure point, as superheating occurs without adding pressure. Therefore, the primary characteristic that distinguishes superheated steam is its increased heat energy compared to saturated steam at the same pressure
