Solution 10 Q
Step 1 of 2
We have to explain does an ordinary electric fan cool the air, if not, why use it.
The human body loses the heat by warming the air surrounding the body. If the warm air stays in contact with the body, then the body may not lose further heat. The fan by circulating the air, replaces the warm air surrounding the body with a cooler air so that the cooling continues.
