Basic Theory of Heat Pt 1

Year Published: 1960

Complete Record: Defines heat; traces the history of the study of heat; and explains some of the physical effects heat has on matter. Uses animation to describe the now rejected caloric theory, and Joule’s demonstration of the mechanical equivalent of heat. A special apparatus is used to show the interrelations of temperature, pressure, and volume in kinetic theory of heat. Melting points of crystalline and non-crystalline substances are discussed; vaporization and liquification are related to thermal energy; and the nature of temperature and heat are contrasted. Manufacturing of mercury thermometers is highlighted. (Heat and Cold series).
