The humid volume may be increased by increasing the____________________?
Correct answer: C. Both A. and B.
- A. Temperature at constant humidity
- B. Humidity at constant temperature
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Humid volume increases with temperature because the gas expands, and it also increases with humidity because water vapour adds volume per unit mass of dry gas. Therefore, both changes increase the humid volume.
