The wetability of a surface by a liquid depends primarily on
Options
(a) surface tension
(b) density
(c) angle of contact between the surface and the liquid
(d) viscosity
Correct Answer:
angle of contact between the surface and the liquid
Explanation:
Wetability of a surface by a liquid primarily depends on angle of contact between the surface and liquid. If angle of contact is acute liquids wet the solid and vice-versa.
