Battino, Rubin; Letcher, Trevor M. – Journal of Chemical Education, 2008
The cryophorus dramatically demonstrates the cooling effect of evaporation. This article describes some simple and easy-to-make cryophoruses, ideal for demonstrating evaporative cooling to students at all levels. The most dramatic effects occurred with cyclohexane and benzene, with water generally freezing more slowly. (Contains 4 notes, 2 tables,…
