Question

Under which conditions, will a liquid make the surface it touches wet?

Answer 1

The degree of wetting is determined by a force balance b/w adhesive and coherive forces, and the contact angle provides an inverse measure of wettability

= Degree of wetting is maximum =

Perfect wetting

The degree of wetting is wght

= degree of wetting is law.

=The degree of wetting becomes minimum and surface is said to be perfectly non - wetting.
