Fig. 3-3, p. 80 Diagram of a power plant Infrared image of a house: Diagram showing the energy required to heat and boil water Diagram of conduction set-up: k = thermal conductivity Photos of insulating materials (though having them in studio would be better) Animation of CONVECTION: RADIATION (Electromagnetic) spectrum: Infrared images: Visible light: Infrared light: Which of these metal rods is hot? Diagram or photo of radiator Photo of someone walking on coals. Photo of air conditioner: inside Photo of air conditioner: outside Photo of bicycle tire being pumped up A heat pump (air conditioner, refrigerator) uses the trick that gases become hot when compressed, cold when expanded. 1. HOT HIGH PRESSURE A heat pump (air conditioner, refrigerator) uses the trick that gases become hot when compressed, cold when expanded. 1. HOT 2. Cools off HIGH PRESSURE A heat pump (air conditioner, refrigerator) uses the trick that gases become hot when compressed, cold when expanded. 1. HOT 2. Cools off 3. Ambient HIGH PRESSURE A heat pump (air conditioner, refrigerator) uses the trick that gases become hot when compressed, cold when expanded. 1. HOT 2. Cools off 3. Ambient 4. COLD LOW PRESSURE A heat pump (air conditioner, refrigerator) uses the trick that gases become hot when compressed, cold when expanded. 1. HOT 2. Cools off 3. Ambient 4. COLD 5. Warms up LOW PRESSURE A heat pump (air conditioner, refrigerator) uses the trick that gases become hot when compressed, cold when expanded. 1. HOT 2. Cools off 3. Ambient 4. COLD 6. Ambient 5.
