I think that the mathematical models/equations, rather than the specific software tools that calculate them, would be more interesting when describing how to determine contact angle and surface energies.
Several wiki pages (such as the "Wetting" page) state that the terms "Surface Tension" and "Surface Energy" are interchangeable. With that in mind, is it really necessary to have a page on each? If the two terms are NOT interchangeable, then there needs to be some serious editing on these other pages to clarify which is which. Branfish 12:09, 14 July 2007 (UTC)
In the part concerning surface energy of solids, one finds the relation dG = -p dl + gamma dA : the first and last terms have the dimensionality of energy, while the second not. —Preceding unsigned comment added by 220.127.116.11 (talk) 14:01, 25 January 2010 (UTC)
- P is the tension and has units of force (N). dl has units of length (m). The product is N-m (work) and has units of energy. Bbanerje (talk) 20:39, 1 February 2010 (UTC)
Further literature on the subject
Is there any litterature that I should look out for if I want to learn more about surface tension and surface energy. — Preceding unsigned comment added by 18.104.22.168 (talk) 16:01, 18 October 2014 (UTC)
cutting to make surfaces
I'm not sure that the discussion on cutting apart a solid is helpful, it provides no intuition. The usual explanation for surface energy is not that the bonds have been mechanically ripped apart. Rather it is simply that the matter near the surface is unable to organize and bond in the same manner as it does in the bulk. (How it got there is unimportant.)
