Does a common electric fan cool the air in a room? If not, then why is it used in an overly warm room?
Solution 11E Step 1: If the room is isolated from the surrounding air, the temperature of the room will increase slightly due to the faster movement of air molecules and the radiant energy from the fan. So, a common electrical fan increases the temperature of an isolated room if it works. We are using the fan to reduce our body temperature or to move the air. If we feel hot, we will use the fan. But, actually the fan initiates the movement of air molecules....
