EXPOSING HIDDEN ENERGY TRANSFERS WITH INEXPENSIVE THERMAL IMAGING CAMERAS

摘要

Energy is never created or destroyed——so the saying goes. Many students will memorize this statement, but few adhere to it when making sense of everyday phenomena (Chabalengula, Sanders, and Mumba 2012). After all, it seems that energy pops into and out of existence all the time. Hot drinks get cold, sparks seem to form from nowhere and then disappear, and the energy we get from food and fuel is exhausted.
