You are presented with the question "What happens when fans circulate more air?" and the following answer choices: 
- 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

Now knowing that the vanes rotating in an electric fan causes air to move and fans move air, increasing evaporation and decreasing temperature, choose the best answer.


 

    decrease in temperature
