Surface Tension at Critical Temperature: Contact Angle?

i_island0 · Nov 17, 2008

At critical temperature, the surface tension becomes zero.
What happens to contact angle at critical temperature?

It's probably not a meaningful concept. Since there is no energy cost associated with creating a material interface (and no pressure jump across a curved surface) it's not clear what 'wetting' means.
