Writing & Language

To show how a common desk fan cools a person, Rhett Allain, a physics professor and writer for Wired magazine, performed a simple experiment. He wet a paper towel with warm water and wrapped it around a thermometer. Allain wrapped a second thermometer in a dry paper towel. Afterward, he set both thermometers in front of a fan. Initially the fan was turned off. The temperature of the thermometer wrapped in the wet paper towel decreased -- at first rapidly, then more slowly -- and eventually dropped below room temperature. After the fan was turned on, the temperature of the wet thermometer underwent another rapid decrease. By contrast, the temperature of the thermometer wrapped in the dry paper towel barely changed during the entire experiment. This experiment demonstrated the power of evaporation to cool wet objects, such as a sweaty person, and the role of a fan in making evaporation more effective.

A.NO CHANGE
B.but eventually dropping
