In a very old tale, a nymph, a simple imaginary woodland creature, is walking through the forest in a snowstorm. She meets a traveler wandering lost and cold. The nymph feels sorry for the man and invites him to her home for lunch. The man accepts, then sits by the nymph’s fire, blowing on his fingers to warm them. The nymph asks the man what he is doing. She’s very impressed when she hears the man can warm himself that way. Lunch is served. The man blows on his soup and tells the nymph that he is cooling it down. The nymph is astonished. How can the same mouth, she asks, blow both hot and cold? Angered at the man’s double dealing, she drives him back out into the forest. Because the nymph is imaginary, and the tale is set in a long-ago time, the nymph does not know about the relationship between kinetic and thermal energy. How could analyzing that relationship have helped the nymph and saved the lost man from being sent back out into the storm? (2 points)

Analyzing the relationship between kinetic and thermal energy could have helped the nymph understand that the traveler was not being deceitful, but rather utilizing the same physical principle in different ways. Kinetic energy relates to the movement of molecules, and thermal energy is a measure of that movement in terms of heat. When the man blew on his fingers, he was rapidly moving air (kinetic energy) to warm them up, transferring heat to his skin. Similarly, when he blew on his soup, he was again using air movement to cool the soup by facilitating heat transfer away from it, lowering its temperature.

By appreciating this relationship, the nymph could have realized that the man’s abilities to create warmth and coolness were not contradictory but rather demonstrated his understanding of energy transfer. This insight might have led her to empathize with him, recognizing that he was simply utilizing natural processes rather than deceiving her. Instead of driving him back into the storm, she may have chosen to keep him warm and share more of her wisdom about the forest, fostering a bond that could have led to a deeper understanding of each other and the nature around them.
