In case of an unsaturated mixture of gas and vapor, the percentage saturation is __________________ its relative saturation?
Correct answer: C. Lower than
- A. Equal to
- B. Higher than
- C. Lower than
- D. Either A. or B., depends on the mixture composition
Explanation
For an unsaturated gas-vapour mixture, percentage saturation based on humidity is lower than relative saturation based directly on vapour partial pressure. The difference arises because humidity uses the dry-gas pressure in its denominator.
