Question

Joan completed a science experiment using a sling psychrometer. She made the following notes in her science journal. Joan made one mistake while recording her notes. Which sentence reveals her mistake? It felt hot in the science lab, and my skin felt sticky. I ran the experiment by spinning the sling psychrometer. There was a very small difference in the dry bulb and wet bulb temperatures. This is the result of the water on the wick of the wet bulb evaporating rapidly. The evaporation caused a slight drop in the level of mercury in the wet bulb. I conclude that the relative humidity in the lab is very high.
