| Summary |
"The accurate determination of surface tension is of importance in the investigation of theories of surface structure, the structure of liquids, molecular cohesion, in the study of colloids, especially in physiological work, and in various lines of technical chemistry. The two methods most commonly used for determining surface tension are the capillary rise method and the drop weight method. The theory of the former is simple, but its technique is difficult. Its use in some cases is the cause of errors as high as 30%, due to its inapplicability to certain classes of substance, and is much more sensitive to the action of impurities. The drop weight method is applicable to a wide range of liquids and the experimental work is not difficult. As a result of the development of this method by Harkins and Brown, the accuracy of this method is more reliable"--Introduction, leaf 1. |
