Abstract

Whenever the subject of undercooling of a liquid is taken up in a physics text, some such statements as those quoted appear in the discussion. The difficulties of getting a successful mass demonstration of the undercooling of water are well known. Hence it was thought worthwhile to report one of the interesting cases of water undercooling under what seem to be most unfavorable circumstances. In carrying on investigations of the operating characteristics of home freezers in the United States Bureau of Human Nutrition and Home Economics, one of the tests includes the freezing of a volume-capacity load with water as the test material. The cartons used are pint, paraffined, nested, cardboard containers with disc lids. Copper-constantan thermocouples are used in connection with 16-point Brown Electronik temperature-recording potentiometers, each recording its series of 16 points in some few seconds less than one minute. Hence the temperatures at each location can be followed quite closely.
