Question

select the correct answer. harry uses a sling psychrometer to measure relative humidity near his school. the dry - bulb temperature reads 58°f, and the wet - bulb 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 harrys school than at robertas house. b. the relative humidity is higher at robertas house than at harrys school. c. the relative humidity is the same at harrys school and robertas house. d. the relative humidity is 45% at harrys school and 50% at robertas house.

Explanation:

The closer the wet - bulb temperature is to the dry - bulb temperature, the higher the relative humidity. At Harry's school, the dry - bulb temperature is 58°F and the wet - bulb is 45°F. At Roberta's house, the dry - bulb is 58°F and the wet - bulb is 52°F. Since 52°F is closer to 58°F than 45°F is to 58°F, the relative humidity is higher at Roberta's house.

Answer:

B. The relative humidity is higher at Roberta's house than at Harry's school.
