The primary difference between saturated and superheated steam is what?

Correct Answer: Option C — Saturated steam only exists at a given temperature and pressure, while superheated steam can undergo slight changes and still remain as steam

Saturated steam exists at the boiling point of water for a given pressure, meaning any heat loss results in condensation. Superheated steam is heated beyond the saturation temperature, providing a margin of safety where the steam remains dry even if it loses some heat, increasing efficiency and preventing turbine blade erosion.
