Excerpt from Wettability of Coal, Graphite, and Naphthalene as Measured by Contact Angles Wettability of a solid surface by a liquid can be most easily pictured in terms of the contact angle. If the angle between the solid and liquid surfaces as measured through the liquid is small, the wettability of the surface is rather large. Conversely, a large angle indicates that the solid surface is relatively less wettable insofar as the given liquid is concerned.
