Question

Relation between contact angle hysteresis and contact line motion

Answer 1

$\huge{\mathfrak{\purple{Answer}}}$

->>

While evaluating the surface wettability by contact angle, a term can be also studied named as contact angle hysteresis, which is the difference between the advancing and the receding contact angles on the fabric surface. One of the reasons of contact angle hysteresis is the surface roughness.
