The vanes rotating in an electric fan causes air to move.
Fans move air, increasing evaporation and decreasing temperature.
The more air a fan circulates, the greater the decrease in temperature.
What happens when fans circulate more air?

(1) the production of heat
(2) prevent heat loss
(3) rapid expansion
(4) decrease in temperature
(5) it flows to a lower level
(6) heat produced
(7) A transportation fuel
(8) depress neuronal excitability
