Conceptual Physics Alive: Heat, Temp and Expansion

Conceptual Physics Alive: Heat, Temp and Expansion includes a digital video and questions set with answers. Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, 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 Heat, Temp and Expansion Includes: Hewitt begins by comparing internal energy and temperature. Thermometer construction discussed. Celsius and Fahrenheit scales compared. High temperature but low internal energy 4th-of-July-type sparklers. Specific heat capacity. Water's high specific heat, with examples. Aluminum's low specific heat. Specific heat of foods. Example of water's high specific heat: Hot water bottle during Hewitt's childhood on cold Boston winter nights. Glo
