Why does increasing the airflow over your face make you cooler? Why does getting your finger wet and then increasing the airflow result in an even cooler sensation? Why doesn’t the pen/pencil change temperature at all?
Airflow over the face increases the rate of evaporation of moisture(sweat) and that cools the face. Same thing for the finger. I don't know what you mean with the pen/pencil.
