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
Correct answer is C
| 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, the relative humidity increases steadily
