The vanes rotating in an electric fan causes air to move, and fans move air, increasing evaporation and decreasing temperature. Given these facts, what happens when fans circulate more air among the following options:
- the production of heat
 - prevent heat loss
 - rapid expansion
 - decrease in temperature
 - it flows to a lower level
 - heat produced
 - A transportation fuel
 - depress neuronal excitability


 

    decrease in temperature
