You went inside a closed room occupied with several people. You noticed that despite the number of people inside, the room is still cool even though there are no air conditioners, except for a weird stand fan which amazingly cools the air it blows. After further inspection of the fan, you noticed that it does not have a compressor (like air conditioning units/refrigerators) but instead it has a water refilling cap. Explain how this water does the cooling, absorbing the heat from occupants without increasing temperature
