In chemical dehumidification of air___________________?
Correct answer: C. Specific humidity decreases & dry bulb temperature increases
- A. Both specific humidity & dry bulb temperature increases
- B. Both specific humidity & dry bulb temperature decreases
- C. Specific humidity decreases & dry bulb temperature increases
- D. Specific humidity increases & dry bulb temperature decreases
Explanation
Chemical dehumidification uses a hygroscopic absorbent to remove water vapour from air, reducing specific humidity. Absorption is generally exothermic, so the dry-bulb temperature rises.
