Two girls walked off the court after a tough basketball workout. Both were dripping with sweat. One girl said to the other, "I have heard that sweating
helps keep you cool when you are working hard. Could that be right?"
The second girl responded, "I think it has something to do with
condensation of water on your skin, but I'm not sure how it works."
What would you tell the girls to help them better understand sweating and
cooling?
