Dry
Day 1 – 30°C | Day 2 – 29°C | Day 3 – 25°C
Wet
Day 1 – 22°C | Day 2 – 22°C | Day 3 – 21°C
The reading above are for three consecutive days from a wet and dry bulb hygrometer. It can be concluded that the relative humidity for the three days
- decreased steadily
- remained unchanged
-
increased steadily
- was least on Day 1
The correct answer is: C
Explanation
| 1 | 2 | 3 | |
| Dry | 30°C | 29°C | 25°C |
| Wet | 22°C | 22°C |
21°C |

8°C | 7°C | 4°C |
\(Relative Humidity \propto \frac{1}{temp}\)
Hence, There is a steady increase in the relative humidity between Day 1 and Day 3
