Homework 1. Go to Blackboard and watch the three heat movies uploaded by your instructor. The movies allow you to simultaneously observe heat-based phenomena using both a normal camera and a heat-sensing camera. As seen from the heat-sensing camera, objects that are hotter than their surroundings appear white; the hotter the object, the whiter it looks. a. Watch the "Pouring Hot Water" movie. What type of heat transfer is primarily involved when the hot water is poured into the cool cup: radiation or heat conduction? Explain. b. Watch the "Cold Water Bottle" movie. When the person holds the cold water bottle, parts of the hand - as seen on the heat-sensing camera - change color from white to dark. Use heat transfer concepts to explain why this occurs. c. Watch the "Toaster" movie, and imagine you put your hands above the toaster after it has been turned on. What type of heat transfer would primarily be involved between the toaster and your hand: radiation or heat conduction? Explain
