Harry uses a sling psychrometer to measure relative humidity near his school. The dry bulb temperature reads 58°F, and the wet b
ulb reads 45°F. At the same time, his cousin Roberta uses her sling psychrometer to measure the relative humidity near her house. The dry bulb temperature reads 58°F, and the wet bulb reads 50°F. What can you conclude from the values? A.
The relative humidity is higher at Harry’s school than at Roberta’s house.
B.
The relative humidity is higher at Roberta’s house than at Harry’s school.
C.
The relative humidity is the same at Harry’s school and Roberta’s house.
D.
The relative humidity is 45% at Harry’s school and 50% at Roberta’s house.
And the answer is not A
Answer: A.The relative humidity is higher at Harry’s school than at Roberta’s house.
Explanation:
Relative humidity simply tells us the amount of water vapor that is in the air, when it's being compared to the amount of water vapor that can be held at that particular temperature.
Since the dry bulb temperature reading of both Harry and Roberta is 58°F but wet bulb reads 45°F for Harry and 50°F for Roberta, we can posit that the relative humidity is higher at Harry’s school than at Roberta’s house.
