Quick check from College Physics, 14.6 Convection

Convection: quick check

Explain why using a fan in the summer feels refreshing!

Answer it in your own words before you look.

Answer
Using a fan increases the flow of air: warm air near your body is replaced by cooler air from elsewhere. Convection increases the rate of heat transfer so that moving air “feels” cooler than still air.

How did it go?
