Surface Tension Values as Obtained by Different Methods

Surface Tension Values as Obtained by Different Methods 

The surface tension of a pure liquid should and does come out to be the same irrespective of the method used, although difficulties in the mathematical treatment of complex phenomena can lead to apparent discrepancies. In the case of solutions, however, dynamic methods, including detachment ones, often tend 

The data given in Table II-4 were selected with the purpose of providing a working stock of data for use in problems as well as a convenient reference to 

Derive Eq. II-3 using the surface tension point of view. Suggestion Consider the sphere to be in two halves, with the surface tension along the join balancing the force due to AP, which would tend to separate the two halves. 

Show that the second term in Eq. 11-15 does indeed correct for the weight of the meniscus. (Assume the meniscus to be hemispherical.)
