Conceptual Physics Alive: Heat

Master teacher Paul Hewitt teaches Conceptual Physics. Observe Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. DVD Includes 4 Episodes: Episode 1: Heat, Temperature, and Expansion: Temperature and heat are distinguished from each other. The expansion of solids, liquids, and gases is compared. A discussion on specific heat capacity leads to the physics of a freezing lake. Demonstrations using liquid nitrogen show the effects of low temperatures. Segment length: 44 minutes Episode 2: Heat Transfer: Conduction is related to many everyday examples and is demonstrated by boiling water under a variety of conditions. Convection is shown with a pressure cooker. Radiation is related to Newton's law of cooling. Segment length: 45 minutes Episode 3: Heat Radiation: The temperature dependence of radiation frequencies are related to the greenhouse effect. The way in which sunlight spreads differently over parts of the earth helps explain the warmth of
