Materials and methods

Principles of method if other than guideline:
Surface tension determination was made by the maximum bubble pressure method of Sugden in which a glass bubbler was employed. A cathetometer was used to find the manometer levels, and highly purified benzene was the standardizing liquid for determining the apparatus constant from the diameter of the smaller bubbler tube as measured by a filar micrometer.
