Percentage saturation of a vapor bearing gas is always _____________ the relative saturation?
Correct answer: C. Smaller than
- A. Higher than
- B. Equal to
- C. Smaller than
- D. Either A. or B.; depends on the system
Explanation
Percentage saturation is based on humidity, while relative saturation is based on the ratio of vapour partial pressure to saturation vapour pressure. At the same temperature, the humidity ratio relationship makes percentage saturation smaller than relative saturation.
