Which of the following approaches the ideal gas behavior most closely ?
Correct answer: C. Superheated steam
- A. Wet steam
- B. Saturated steam
- C. Superheated steam
- D. Saturated water
Explanation
Superheated steam is at a temperature above its saturation temperature and contains less liquid-like character, so its properties approach those of an ideal gas. Wet and saturated steam still has significant intermolecular effects and, in the wet case, liquid droplets.
