HOT AND COLD

Temperature, its manifestations and effects, are throughly scrutinized in this illuminating text. Defining temperature as a continuum, the author discusses the molecular components of heat and cold, their materialization in extreme conditions such as fire and ice, electricity, and the uses to which man-controlled heat may be put. Irving Adler, author of more than a dozen science books, treats this essential subject methodically and in a manner which should both interest and inform.
